ABSTRACT

Benign paroxysmal positional vertigo is the most common cause of peripheral vertigo. It is characterized by short and recurrent episodes of vertigo, trigged by specific head movements that displace otoconia within the semicircular canals. The movement of dislodge otoconia from the utricle cause abnormal positional endolymphatic currents. Primary treatment involves reposition maneuvers aimed at moving the displaced otoconia out the affected canal, therefore correct identification of the affected canal is essential for the diagnosis. The posterior semicircular canal (PSC) is the most frequently affected due to its spatial orientation and the force of gravity. Recent technological advances have allowed for better assessment of positional nystagmus during diagnostic and therapeutic maneuvers, revealing various possible scenarios of PSC involvement. Regarding the PSC, otoconia may be found in different parts of the canal, and not just in the expected location, floating in the long arm of the canal. The understanding of these variants is crucial, as the prognosis and the disease progression differ in such cases. This review aims to describe the six possible variants of PSC involvement described so far.

ABSTRACT

Introducción y objetivo: El objetivo de nuestro estudio fue demostrar las diferencias clínicas entre el vértigo posicional paroxístico benigno (VPPB) idiopático y secundario a síndrome vestibular agudo periférico (SVA). Método: Estudio de casos y controles, retrospectivo. La recolección de datos fue tomada de historias clínicas de nuestro hospital. Datos demográficos y clínicos de pacientes con diagnóstico de VPPB idiopático y secundario a SVA, fueron recogidos para el análisis. Además, en el grupo de los casos, se realizó una correlación entre el déficit vestibular periférico, medido a través del video head impulse test (vHIT), y el número de maniobras y tiempo hasta la resolución del VPPB. Resultados: Se incluyeron 72 pacientes, 64% mujeres. En el grupo control se incluyeron 50 pacientes con VPPB idiopático y 22 con VPPB secundario a SVA en el grupo de los casos. En el VPPB secundario, el canal semicircular posterior estuvo afectado en el 100% (OR: 1.2; IC 95% [1,088 - 1,436]). Ambos grupos mostraron una resolución del vértigo del 90% y 89%, respectivamente. El grupo de VPPB secundario tuvo 4 veces más riesgo de recurrencia (OR: 4.18; IC 95% [1.410 - 12.406]); necesitaron más maniobras (3.32 ± 2.2 vs. 1.7 ± 1.3, p = 0.004) y tiempo (61.9 días ± 73.1 vs. 12.9 días ± 9.6, p = 0.007) para la resolución del VPPB. Se encontraron correlaciones significativas entre la diferencia de ganancia media del reflejo vestíbulo-ocular (RVO) y el número de maniobras (r = 0.462, p = 0.030) y el tiempo hasta la resolución (r = 0.577, p = 0.008). Discusión: Existen diferencias clínicas entre el VPPB idiopático y secundario a SVA, principalmente en términos de canal semicircular afecto, mayor número de maniobras y tiempo en días hasta la resolución del VPPB. Además, de determinar que a mayor déficit vestibular en un paciente con VPPB secundario a SVA, necesitará un mayor número de maniobras y un tiempo prolongado hasta la resolución del VPPB. Conclusiones: ... (AU)


Introduction and Objective: The aim of our study was to demonstrate the clinical differences between idiopathic benign paroxysmal positional vertigo (BPPV) and BPPV secondary to acute peripheral vestibular syndrome (APVS). Method: Retrospective case-control study. Data collection was obtained from medical records at our hospital. Demographic and clinical data of patients diagnosed with idiopathic BPPV and BPPV secondary to APVS were collected for analysis. Additionally, in the case group, a correlation was performed between peripheral vestibular deficit, measured through the video head impulse test (vHIT), and the number of maneuvers and time until resolution of BPPV. Results: Seventy-two patients were included, with 64% being women. The control group included 50 patients with idiopathic BPPV and 22 with BPPV secondary to APVS in the case group. In secondary BPPV, the posterior semicircular canal was affected in 100% of cases (OR: 1.2; 95% CI [1.088 - 1.436]). Both groups showed a vertigo resolution rate of 90% and 89%, respectively. The secondary BPPV group had a 4-fold higher recurrence risk (OR: 4.18; 95% CI [1.410 - 12.406]); they required more maneuvers (3.32 ± 2.2 vs. 1.7 ± 1.3, p = 0.004) and more time (61.9 days ± 73.1 vs. 12.9 days ± 9.6, p = 0.007) for BPPV resolution. Significant correlations were found between the difference in mean gain of the vestibulo-ocular reflex (VOR) and the number of maneuvers (r = 0.462, p = 0.030) and the time until resolution (r = 0.577, p = 0.008). Discussion: Clinical differences exist between idiopathic BPPV and BPPV secondary to APVS, primarily in terms of the affected semicircular canal, a higher number of maneuvers, and a longer time in days until BPPV resolution. Furthermore, it was determined that a greater vestibular deficit in a patient with secondary BPPV to APVS requires a higher number of maneuvers and an extended time until BPPV resolution. Conclusions: ... (AU)

ABSTRACT

Se presenta el caso clínico de una fémina de 39 años de edad, quien fue asistida en el Hospital General Docente Guillermo Domínguez López de Puerto Padre, provincia de Las Tunas, por presentar una masa tumoral de aproximadamente 10 cm en el hipogastrio. Luego de realizados el examen clínico y los estudios complementarios pertinentes, se decidió practicar la resección completa del tumor. Durante el procedimiento quirúrgico, se tomó muestra para biopsia cuyo resultado indicó la existencia de un leiomioma simplástico en el espacio de Retzius. La paciente evolucionó satisfactoriamente y egresó de la institución a los 5 días, pero se continuó su seguimiento por consulta externa.


The case report of a 39 years woman is presented, who was assisted in Guillermo Domínguez López Teaching General Hospital from Puerto Padre, Las Tunas province, due to a tumoral mass of around 10 cm in the hypogastrium. After the clinical exam and the pertinent complementary studies, it was decided to practice the complete resection of the tumor. During the surgical procedure, a sample for biopsy was taken which result indicated the existence of a symplastic leiomyoma in the Retzius space. The patient had a favorable clinical course and she was discharged from the institution 5 days later, but continued with follow up in outpatient department.

ABSTRACT

OBJECTIVES: Vestibular evoked myogenic potentials (VEMPs) are useful for studying the disturbances along nerve pathways implicated in the transmission of neurological information from otolithic organs related to vestibular function. This study aims to determine the differences in VEMPs in patients affected with benign paroxysmal positional vertigo (BPPV). METHODS: We recruited 36 patients, 9 diagnosed with recurrent BPPV (rBPPV), 9 with only one episode of vertigo (iBPPV), and 18 as a control group. We performed cervical and ocular VEMPs (cVEMPs and oVEMPs). RESULTS: We observed differences in asymmetry ratio, which was 41.82% in cVEMPs in iBPPV and 68.27% in oVEMPs in rBPPV, while no asymmetry was found in control cases. Also, there was a lack of both VEMP responses in 22.2% of cases and an absence of cVEMP in 11.1% in iBPPV; in rBPPV, 11.1 % presented no responses in cVEMPs or oVEMPs, 22.2% showed no oVEMP, and 11.1% showed no cVEMP. These values were normal in the control group. CONCLUSION: The value of VEMPs in BPPV demonstrates the implication of vestibular damage, mainly utricle damage. For better sensitivity in detecting otolith abnormalities, we should perform oVEMPs and cVEMPs in recurrent BPPV and early stages of BPPV.

ABSTRACT

La adenomatosis erosiva es una neoplasia benigna poco frecuente que afecta al pezón. Caracterizado por erosión, telorrea, telorragia, nodularidad, prurito y eritema, ocasionando un proceso destructivo progresivo del pezón, el cual puede ser confundido con la enfermedad de Paget; motivo por el cual el conocimiento de esta enfermedad es fundamental para evitar el sobretratamiento quirúrgico. Presentamos el caso de una paciente de 35 años diagnosticada y tratada con cirugía, así como la revisión de la literatura de esta entidad. (AU)


Erosive adenomatosis is a rare benign neoplasm that affects the nipple. Characterized by erosion, telorrhoea, telorrhagia, nodularity, pruritus and erythema, causing a progressive destructive process of the nipple, which can be confused with Paget's disease; which is why knowledge of this pathology is essential to avoid surgical overtreatment. We present the case of a 35-year-old patient diagnosed and treated with surgery, as well as a review of the literature on this entity. (AU)

ABSTRACT

El vértigo posicional paroxístico benigno (VPPB) es un síndrome vestibular episódico (SVE) que es reconocido por ser el trastorno más frecuente observado en la clínica, siendo de buena y pronta resolución en la gran mayoría de los casos. Sin embargo, pueden presentarse variantes muy poco habituales o atípicas, donde el canalith jam es una de las formas más resistentes al tratamiento mediante maniobras de reposición, y por lo mismo, el reconocimiento adecuado de este cuadro es esencial para su correcto abordaje. Se presentan dos casos de VPPB con canalith jam en el CSC horizontal y se proponen cinco criterios diagnósticos para su identificación.


Benign paroxysmal positional vertigo (BPPV) is an episodic vestibular syndrome (EVS) that is recognized for being the most frequent disorder observed in the clinic, with good and prompt resolution in the vast majority of cases. However, very unusual or atypical variants can occur, where the canalith jam is one of the forms most resistant to treatment by means of repositioning maneuvers, and for the same reason, the adequate recognition of this condition is essential for its correct approach. Two cases of BPPV with canalith jam in the horizontal semicircular canal and five diagnostic criteria for its identification are presented.

ABSTRACT

Introducción: El traumatismo craneoencefálico (TCE) puede generar vértigo, mareo e inestabilidad. Posibles causas otorrinolaringológicas son el vértigo postural paroxístico benigno (VPPB) que constituye el diagnóstico más frecuente, y la hipofunción vestibular. Objetivo: Describir la prevalencia de hipofunción vestibular en un grupo de pacientes con VPPB asociado a TCE. Material y Método: Estudio retrospectivo de pacientes con VPPB asociado a TCE que requirieron maniobra de reposición (MRP) entre los años 2017 y 2021. La información clínica, características clínico-demográficas, hallazgos en pruebas de función vestibular y número de MRP fueron evaluados. Resultados: Se incluyeron 48 pacientes con una edad promedio de 60,8 ± 16,5 años, siendo un 52% mujeres. La prevalencia de pacientes con paresia vestibular concomitante correspondió al 35,4%. Al comparar al grupo con y sin paresia se observó: (1) en el grupo con paresia fue, significativamente, más frecuente presentar contusión cerebral asociada, 47,1% vs 12,9%; (2) el sexo masculino fue, significativamente, más frecuente en el grupo con paresia, 70,59% vs 35,5%; (3) en ambos grupos, la mediana de MRP fue 1. Conclusión: La presencia de paresia vestibular en pacientes con VPPB secundario a TCE, no es un hallazgo infrecuente, en nuestro estudio, correspondió a un 35,4%, siendo este más frecuente en hombres. Adicionalmente, la contusión cerebral asociada es más frecuente en el grupo con paresia.


Introduction: Head trauma can generate vertigo, dizziness and instability. Possible otorhinolaryngologic causes are benign paroxysmal postural vertigo (BPPV), which is the most frequent diagnosis, and vestibular hypofunction. Aim: To describe the prevalence of vestibular hypofunction in a group of patients with BPPV associated with head trauma. We studied the clinical characteristics, vestibular function test findings and the number of (PRM). Material and Method: Retrospective study of patients with BPPV associated with head trauma who underwent particle repositioning maneuvers (PRM) during the years 2017 to 2021. Clinical characteristics, vestibular function test findings and the number of PRM were evaluated. Results: 48 patents were included. The mean age was 60.8 ± 16.5 years old, 52% were women. The prevalence of patients with concomitant vestibular paresis was 35.4%. When comparing the groups with and without paresis the following was observed: (1) associated brain contusions were significatively more frequent in the paresis group, 47.1% vs 12.9%; (2) male sex was significatively more frequent in the paresis group, 70.59% vs 35.5%; (3) in both groups, the median of needed PRM was 1. Conclusion: The presence of vestibular paresis in patients with BPPV secondary to head trauma is not an infrequent finding. In our study, its prevalence was 35.4%, being significatively more frequent in men. Also, associated brain contusions were significatively more frequent in the paresis group.

ABSTRACT

Background and objectives The results of previous PET-CT studies are contradictory for discriminating malignant from benign pleural effusions. We purpose to develop a PET-CT score for differentiating between benign and malignant effusions. Patients and methods We conducted a prospective study of consecutive patients with pleural effusions undergoing PET-CT from October 2013 to October 2019 (referral cohort). PET-CT scan features evaluated using the SUV were: linear thickening; nodular thickening; nodules; masses; circumferential thickening; mediastinal and fissural pleural involvement; intrathoracic lymph nodes; pleural loculation; inflammatory consolidation; pleural calcification; cardiomegaly; pericardial effusion; bilateral effusion; lung mass; liver metastasis and other extra-pleural malignancy. The results were validated in an independent prospective cohort from November 2019 to June 2021. Results One hundred and ninety-nine patients were enrolled in the referral cohort (91 with malignant effusions and 108 benign). The most useful parameters for the development of a PET-CT score were: nodular pleural thickening, pleural nodules with SUV>7.5, lung mass or extra pleural malignancy (10 points each), mammary lymph node with SUV>4.5 (5 points) and cardiomegaly (−1 point). With a cut-off value of >9 points in the referral cohort, the score established the diagnosis of malignant pleural effusion with sensitivity 87.9%, specificity 90.7%, positive predictive value 88.9%, negative predictive value 89.9%, positive likelihood ratio 7.81 and negative likelihood ratio 0.106. These results were validated in an independent prospective cohort of 75 patients. Conclusions PET-CT score was shown to provide relevant information for the identification of malignant pleural effusion (AU)


Antecedentes y objetivos Los estudios PET-TAC previos en el análisis del derrame pleural son contradictorios. Nuestro objetivo es desarrollar una puntuación mediante PET-TAC para diferenciar entre derrames benignos y malignos. Pacientes y métodos Estudio prospectivo en pacientes con derrame pleural a los que se realizó una PET-TAC desde octubre de 2013 hasta octubre de 2019 (cohorte de referencia). Los datos analizados fueron: engrosamiento lineal; engrosamiento nodular; nódulos; masas; engrosamiento circunferencial; afectación pleural mediastínica y cisural; ganglios linfáticos torácicos; loculación pleural; consolidación; calcificación pleural; cardiomegalia; derrame pericárdico; derrame bilateral; masa pulmonar; metástasis hepáticas y otras neoplasias malignas extrapleurales. Se calculó el SUV de todos estos parámetros. Los resultados se validaron en una cohorte independiente. Resultados Se incluyó a 199 pacientes en la cohorte de referencia (91 derrames malignos y 108 benignos). Los parámetros que mostraron más utilidad para discriminar ambos derrames y desarrollar una puntuación fueron: engrosamiento pleural nodular, nódulos pleurales con SUV > 7,5, masa pulmonar o malignidad extrapleural (10 puntos cada uno), ganglio en cadena mamaria con SUV > 4,5 (5 puntos) y cardiomegalia (–1 punto). Con un punto de corte > 9 en la cohorte de derivación, se estableció el diagnóstico de derrame pleural maligno con una sensibilidad del 87,9%, especificidad del 90,7%, valor predictivo positivo del 88,9%, valor predictivo negativo del 89,9% razón de verosimilitud positiva del 7,81 y razón de verosimilitud negativa del 0,106. Estos resultados fueron validados en una cohorte prospectiva independiente de 75 pacientes. Conclusiones Una puntuación basada en PET-TAC proporciona información relevante para el diagnóstico del derrame pleural maligno (AU)

ABSTRACT

Presentamos el caso de un hombre de 61 años en el que se halló de forma incidental un encondroma a nivel proximal de fémur. Tras seguimiento, se observó la estabilidad de la lesión. El encondroma es un tumor de origen cartilaginoso benigno. Se localiza principalmente en las falanges de las manos y los pies, aunque puede observarse en húmero o fémur. Por lo general, es una lesión asintomática y se halla de manera incidental. En las radiografías suelen verse lesiones redondeadas bien definidas con radiolucidez central. Se recomienda el seguimiento con radiografías seriadas para comprobar la progresión o estabilidad de la lesión y hacer su diagnóstico diferencial con el condrosarcoma.(AU)


We report the case of a 61-year-old man in whom an enchondroma was incidentally detected at the proximal level of the femur. After follow-up the lesion was stable. Enchondroma is a benign cartilaginous tumor. It is located mainly in the phalanges of the hands and feet, although it can be seen in the humerus or femur. It is usually an asymptomatic lesion, found incidentally. On x-rays, well-defined round lesions with central radiolucency are usually observed. Follow-up with serial x-rays is recommended to verify the lesion’s course or stability and make its differential diagnosis with chondrosarcoma.(AU)

ABSTRACT

El vértigo posicional paroxístico benigno (VPPB) se caracteriza por episodios cortos y bruscos de vértigo cuando la cabeza se mueve en posiciones específicas. El tratamiento son las terapias de reposición de partículas. En general el VPPB es subdiagnosticado, no reportado y por lo tanto no es tratado de forma adecuada. Presentamos el caso de un paciente con lesión medular y VPPB. Paciente de 72 años que sufre una fractura de C5 y como resultado una lesión medular C5 AIS C que necesitó la fijación quirúrgica. En la unidad de lesionados medulares se documentó VPPB del conducto semicircular lateral izquierdo y se trató mediante el uso de terapias de reposición específicas; el paciente mejoró progresivamente y pudo concluir el tratamiento rehabilitador. Las unidades de lesión medular con acceso a unidades de rehabilitación vestibular pueden realizar el diagnóstico y tratamiento específico del VPPB, minimizando los riesgos para el paciente.(AU)


Benign paroxysmal positional vertigo (BPPV) is characterized by short, sudden episodes of vertigo when the head moves in specific positions. The treatment is particle repositioning maneuvers. BPPV usually is underdiagnosed, unreported and therefore not adequately treated. We present the case of a patient with spinal cord injury and BPPV. A 72-year-old patient who suffered a C5 fracture with spinal cord injury C5 AIS C that required surgical fixation. In the spinal cord injury unit BPPV of the left lateral semicircular canal was documented and treated using specific repositioning maneuvers, the patient progressively improved and was able to complete the rehabilitation treatment. The spinal cord injury unit with access to vestibular rehabilitation units can carry out the diagnosis and specific treatment of BPPV, minimizing the risks for the patient.(AU)

ABSTRACT

El adenoma de pezón es un tumor benigno que se origina en los conductos galactóforos del pezón. El objetivo de nuestro estudio es describir y comparar con la literatura la casuística del adenoma de pezón en nuestro centro, desde enero de 2009 hasta diciembre de 2019. Nuestra serie de casos la forman 5 pacientes. Todos son mujeres, de edades comprendidas entre los 40 y los 82 años. Dos pacientes consultaron por telorragia y las restantes fueron derivadas de atención primaria por lesiones en el pezón de nueva aparición. Las pruebas de imagen no presentaron hallazgos específicos. El resultado de la biopsia preoperatoria fue diagnóstico de adenoma de pezón en todos los casos. En todos los casos se realizó exéresis simple de la lesión. Ningún paciente presentó recidiva ni aparición de carcinoma con una media de seguimiento de 31 meses. Una paciente falleció por otros motivos. Como conclusión se destaca la importancia de la biopsia y el estudio inmunfenotípico para realizar el diagnóstico diferencial con otras afecciones como la enfermedad de Paget o el carcinoma de pezón. El manejo quirúrgico no muestra cambios respecto a la literatura, prefiriendo opciones más conservadoras como la escisión local con resultados excelentes a largo plazo. (AU)


Nipple adenoma is a benign tumor that originates in the milk ducts of the nipple. The objective of our study is to describe and compare the casuistry of nipple adenoma in our center between January 2009 and December 2019 with the literature. Our case series consists of 5 patients. They are all women, aged between 40 and 82 years. Two patients consulted for telorrhagia and the rest were referred from primary care for new-onset nipple lesions. Imaging tests did not present specific findings. The result of the preoperative biopsy was diagnostic of nipple adenoma in all cases. In all cases, simple exeresis of the lesion was performed. No patient presented recurrence or appearance of carcinoma with a mean follow-up of 31 months. One patient died for other reasons. In conclusion, the importance of the biopsy and the immunophenotypic study to perform the differential diagnóstico with other pathologies such as Paget's disease or nipple carcinoma should be highlighted. Surgical management shows no changes compared to the literature, preferring more conservative options such as local excision with excellent long-term results. (AU)

ABSTRACT

Introducción y objetivo: El Vértigo Posicional Paroxístico Benigno (VPPB) es más frecuente dentro del subgrupo de pacientes con Enfermedad de Menière (EM). El presente estudio tiene como objetivo describir las características clínicas tanto del VPPB como de la EM cuando se encuentran asociados. Método: Realizamos un análisis retrospectivo de 22 pacientes con EM diagnosticados de VPPB entre el 1999 y el 2021 en el Complejo Asistencial Universitario de Salamanca. Se recogieron variables clínicas, tanto de las características del VPPB como de la EM. Resultados: En nuestra base de datos, el 66,66 % de los 22 pacientes eran mujeres con una edad media de 59,33 años. El canal semicircular afecto con más frecuencia fue el posterior derecho. En cuanto al VPPB, un 19% se trata de VPPB multicanal, en casi la mitad (47,62%) se tuvieron que realizar más de tres maniobras para solucionarlo y tardó más de un mes en resolverse en más de la mitad (57,14%). Por otro lado, la EM era bilateral en el 19% de los pacientes, con un tiempo de evolución desde el diagnóstico de más de tres años en el 71,42%. Un tercio de los pacientes había presentado más de 10 crisis en los últimos seis meses, y fluctuación en la audición. En base a estos resultados, parece que los pacientes con EM avanzada tienen más probabilidades de presentar VPPB y con peor resultado en su tratamiento. Conclusión: La aparición conjunta del VPPB y la EM podría afectar al pronóstico de ambas patologías por separado. (AU)


Introuction and objective: Benign Paroxysmal Positional Vertigo (BPPV) is more frequent within the subgroup of patients with Menière's Disease (MD). The present study aims to describe the clinical characteristics of both BPPV and MD, when they are associated. Method: We carried out a retrospective analysis of 22 patients with MD diagnosed with BPPV between 1999 and 2021 at the University Assistance Complex of Salamanca. Clinical variables were collected, both from the characteristics of BPPV and MD. Results: In our database, 66.66% of the 22 patients were women with a mean age of 59.33 years. The most frequently affected semicircular canal was the posterior right. Regarding BPPV, 19% are multichannel BPPV, in almost half (47.62%) more than three maneuvers had to be performed to solve it and it took more than a month to resolve it in more than half (57.14%). On the other hand, MD was bilateral in 19% of patients, with a time since diagnosis of more than three years in 71.42%. A third of the patients had presented more than 10 crises in the last six months, and fluctuation in hearing. Based on these results, it appears that patients with advanced MD are more likely to have BPPV and have a worse treatment outcome. Conclusion: The joint appearance of BPPV and MD could affect the prognosis of both pathologies separately. (AU)

ABSTRACT

El hemangioma coroideo es un tumor vascular benigno dependiente de la circulación coroidea. Se distinguen 2tipos de lesiones: circunscrita, variante más frecuente, y difusa, asociada normalmente al síndrome de Sturge-Weber. El hemangioma coroideo circunscrito se presenta como una masa anaranjada que puede aparecer de manera asintomática, sin embargo, cuando produce síntomas, lo más frecuente es la disminución de la agudeza visual debido a un desprendimiento de retina neurosensorial. Debido a su carácter benigno solo deberían ser subsidiarios de tratamiento aquellos que produzcan síntomas. El conocimiento de esta enfermedad y su correcto diagnóstico diferencial es muy relevante para establecer el diagnóstico y tratamiento adecuado y evitar tratamientos innecesarios. En la actualidad existe una gran variedad de pruebas de imagen de diagnóstico multimodal que nos permiten identificar y realizar un seguimiento adecuado de este tumor. Además, en los últimos años, gracias al empleo de la terapia fotodinámica, se ha producido un cambio en el paradigma del tratamiento de estas lesiones, lo cual ha supuesto una mejora significativa en el pronóstico visual de estos pacientes. Esto se ha debido al empleo de la terapia fotodinámica, como tratamiento de elección para el hemangioma coroideo circunscrito (AU)


Choroidal hemangiomais a benign vascular tumor dependent on the choroid. Two types of lesions are distinguished: circumscribed, the most frequent variant, and diffuse, normally associated with Sturge-Weber syndrome. The circumscribed choroidal hemangioma appears as an orange mass that can present asymptomatically, however, when it produces symptoms, the most frequent is decreased visual acuity due to neurosensory retinal detachment. Due to its benign nature, only those that produce symptoms should be eligible for treatment. Knowledge of this pathology and its correct differential diagnosis is very relevant to establish the appropriate diagnosis and treatment, avoiding unnecessary treatments. There is currently a wide variety of multimodal diagnostic imaging tests that allow us to identify and adequately monitor this tumor. In addition, in recent years, there has been a change in the paradigm of the treatment of these tumors thanks to the use of photodinamic therapy, which has led to a significant improvement in the visual prognosis of these patients. This has been due to the use of photodynamic therapy as the treatment of choice for circumscribed choroidal hemangioma (AU)

ABSTRACT

Introducción No se ha determinado la evolución de los pacientes con derrames pleurales idiopáticos con un seguimiento a largo plazo. Métodos Entre octubre de 2013 y junio de 2021 se hizo un seguimiento prospectivo de todos los pacientes con derrame idiopático mediante exploración clínica y estudios de imagen al cabo de 1, 3 y seis meses y cada seis meses durante un mínimo de un año. Resultados Veintinueve pacientes fueron diagnosticados de derrame idiopático y objeto de seguimiento. Durante el seguimiento se detectó un mesotelioma en dos pacientes al cabo de siete y 18 meses; en uno de ellos se observó líquido pleural teñido de sangre y el otro refirió una pérdida de peso de 10%. En ninguno de los pacientes con derrame que cubriera menos de dos tercios del hemitórax y sin síntomas constitucionales ni aparición de líquido teñido de sangre se diagnosticó un mesotelioma. La mayoría de los derrames desaparecieron o mostraron una clara mejoría en los primeros seis meses. Conclusiones Los pacientes sin pérdida de peso y con derrames no hemáticos pequeños pueden beneficiarse de un tratamiento conservador y un seguimiento clínico-radiológico (AU)


Introduction Long-term follow-up course for patients with idiopathic pleural effusions has not been established. Methods From October 2013 to June 2021 all patients with idiopathic effusion were prospectively followed up with clinical examination and imaging at 1,3,6 and every 6 months for a minimum of 1 year. Results Twenty-nine patients were diagnosed with idiopathic effusion and followed up. Mesothelioma was detected during the follow-up in two patients at 7 and 18 months, one of whom had blood-tinged pleural fluid and the other reported a 10% weight loss. Mesothelioma was not diagnosed in any of the patients with effusion covering less than two thirds of the hemithorax, and without constitutional symptoms or a blood-tinged fluid appearance. Most of the effusions resolved or showed a clear improvement in the first six months. Conclusions Patients without weight loss and with small, non-hematic effusions, may benefit from conservative treatment and clinical-radiological follow-up (AU)

ABSTRACT

Choroidal hemangioma (CH) is a benign vascular tumor dependent on the choroid. Two types of lesions are distinguished: circumscribed (CCH), the most frequent variant, and diffuse (DCH), normally associated with Sturge-Weber syndrome. HCC appears as an orange mass that can present asymptomatically, however, when it produces symptoms, the most frequent is decreased visual acuity due to neurosensory retinal detachment. Due to its benign nature, only those that produce symptoms should be eligible for treatment. Knowledge of this pathology and its correct differential diagnosis is very relevant to establish the appropriate diagnosis and treatment, avoiding unnecessary treatments. There is currently a wide variety of multimodal diagnostic imaging tests that allow us to identify and adequately monitor this tumor. In addition, in recent years, there has been a change in the paradigm of the treatment of these tumors thanks to the use of photodinamic therapy, which has led to a significant improvement in the visual prognosis of these patients. This has been due to the use of photodynamic therapy as the treatment of choice for HCC.

ABSTRACT

INTRODUCTION: Long-term follow-up course for patients with idiopathic pleural effusions has not been established. METHODS: From October 2013 to June 2021 all patients with idiopathic effusion were prospectively followed up with clinical examination and imaging at 1, 3, 6 and every 6 months for a minimum of 1 year. RESULTS: Twenty-nine patients were diagnosed with idiopathic effusion and followed up. Mesothelioma was detected during the follow-up in two patients at 7 and 18 months, one of whom had blood-tinged pleural fluid and the other reported a 10% weight loss. Mesothelioma was not diagnosed in any of the patients with effusion covering less than two thirds of the hemithorax, and without constitutional symptoms or a blood-tinged fluid appearance. Most of the effusions resolved or showed a clear improvement in the first six months. CONCLUSION: Patients without weight loss and with small, non-hematic effusions, may benefit from conservative treatment and clinical-radiological follow-up.

ABSTRACT

Introducción: El mucocele apendicular se considera una lesión rara del apéndice que se caracteriza por la dilatación de la luz del órgano con acumulación de moco. Este puede ser benigno o maligno. Objetivo: Caracterizar un caso de mucocele apendicular de comportamiento benigno en un paciente adulto masculino. Presentación del caso: Se asiste a un paciente, en estudio de tumor de vías digestivas, que se interviene quirúrgicamente con cuadro peritoneal agudo hallando masa de localización apendicular. Se realiza apendicectomía convencional y se estudia la pieza por anatomía patológica como mucocele apendicular benigno. La evolución del paciente fue satisfactoria. Conclusiones: Se presenta clínicamente de forma inespecífica, lo que posibilita que su diagnóstico sea intraoperatorio con mayor frecuencia. La estrategia quirúrgica depende de los hallazgos intraoperatorios donde la apendicectomía y la hemicolectomía derecha son las técnicas más utilizadas. El pseudomixoma peritoneal es una complicación temida(AU)


Introduction: Appendiceal mucocele is considered a rare lesion of the appendix characterized by dilatation of the organ lumen with mucus accumulation. It can be benign or malignant. Objective: To characterize a case of appendiceal mucocele with benign behavior in an adult male patient. Case presentation: A patient under study of digestive tract tumor is attended. The patient underwent surgery for having acute peritoneal symptoms; a mass of appendicular location was found. Conventional appendicectomy was performed and the piece was studied by pathological anatomy, being a benign appendicular mucocele. The patient's evolution was satisfactory. Conclusions: This condition is presented clinically in a nonspecific manner, which makes for its diagnosis to be more frequently intraoperative. The surgical strategy depends on the intraoperative findings, in which appendectomy and right hemicolectomy are the most used techniques. Pseudomyxoma peritonei is a feared complication(AU)

ABSTRACT

La fascitis nodular (FN) es una entidad rara que consiste en la proliferación benigna miofibroblástica de la fascia muscular. Se trata de un proceso de etiología desconocida. La presentación clínica habitual consiste en una tumoración de menos de 4 cm de diámetro, indolora, de consistencia dura y de rápido crecimiento. La localización en el territorio craneofacial es muy infrecuente (7-20 %). La fascitis nodular se puede confundir clínica e histológicamente con tumoraciones malignas, por lo que es muy importante un correcto diagnóstico. Presentamos el caso de un paciente varón de 79 años, que consulta por aparición de tumoración paramandibular, de consistencia dura y de dos meses de evolución, asintomática. Tras la realización de pruebas complementarias, el diagnóstico citológico fue de neoplasia mesenquimal con atipias sospechosa de malignidad, recomendándose estudio histológico. (AU)


Nodular fasciitis (NF) is a rare entity consisting of a benign myofibroblastic proliferation of the muscle fascia, a process of unknown etiology. The usual clinical presentation consists of a tumor of less than 4 cm in diameter, painless, of hard consistency and rapid growth. Localization in the craniofacial territory is very infrequent (7-20 %). Nodular fasciitis can be clinically and histologically confused with malignant tumors, so a correct diagnosis is very important. We present the case of a 79-year-old male patient who consulted for the appearance of an asymptomatic paramandibular tumor, with a hard consistency and two months of evolution. After performing complementary tests, the cytological diagnosis was mesenchymal neoplasm with atypia suspicious of malignancy, recommending histological study.In conclusion, an extremely rare giant-sized mucinous adenocarcinoma of the submandibular gland is presented.
