Rol de las imágenes en la patología arterial no ateroesclerótica poco frecuente en el abdomen / Role of images in rare vascular pathology in the abdomen

Resumen La patología arterial no ateromatosa constituye un grupo de patologías poco frecuentes, pero de gran importancia debido a su morbilidad y mortalidad asociadas. La presentación clínica de estas entidades es inespecífica, por lo que el estudio inicial con imágenes es fundamental. Debido a esto, es muy importante reconocer los signos radiológicos característicos de cada una en las diversas modalidades imagenológicas para poder sospechar y orientar el diagnóstico.

Abstract Non-atheromatous arterial pathology constitutes a group of infrequent pathologies but of great importance due to their associated morbidity and mortality. In general, the clinical presentation of these pathologies is quite nonspecific, so the clinician decides to perform imaging studies thinking of more common entities. It is for this reason that it is very important to recognize characteristic radiological signs in the various imaging modalities to be able to suspect and orient a pathology of this kind.

Fístula retroauricular complicada asociada a disgenesia mayor del oído externo. Reporte de un caso / Complicated retroauricular fistula with external ear major dysgenesis. A case report

Las anomalías de las hendiduras y arcos branquiales son la segunda causa más común de lesiones congénitas de cabeza y cuello en niños. Representan el 8% de todas las malformaciones congénitas y el 30% de las de cabeza y cuello. Pueden permanecer asintomáticas o manifestarse como una tumefacción y asociarse a infecciones recurrentes supuradas en la región preauricular, subauricular o retroauricular, en las regiones de la parótida y/o del cuello. Fueron reportados casos asociados a malformaciones óticas.La tomografía computada de alta resolución y la resonancia magnética con gadolinio pueden ayudar al diagnóstico. El tratamiento médico antibiótico está indicado ante una infección aguda, además de incisión y drenaje en los procesos abscedados. El tratamiento definitivo es quirúrgico con la extirpación completa de la lesión. Se presenta a un niño de 6 años de edad con infección aguda en la región retroauricular derecha en el oído disgenésico

Branchial cleft anomalies are the second most common congenital head and neck lesions in children. The first congenital head and neck lesion is thyroglossal duct cysts. First branchial cleft anomalies are rare congenital head and neck malformations (8% of branchial cleft anomalies).The initial clinical manifestation was recurrent infections and/or discharge in auricular, periauricular, parotid or upper neck regions. These anomalies are extremely rare and other associated facial malformations were described.The computed tomography and magnetic resonance can help the diagnosis. The antibiotic treatment is indicated in acute infection. Also, incision and drainage are recommended in abscessed processes.In this report, we present a case of retroauricular sinus infection in a 6-year-old child with congenital ear anomalies

Fístula perilinfática de causa traumática. Reporte de un caso pediátrico / Traumatic perilymphatic fistula. Report of a pediatric case

La fístula perilinfática de causa traumática es una patología poco habitual. En general, es causada por lápices, hisopos, hebillas de pelo y fósforos.Dentro de los síntomas más frecuentes, los pacientes pueden presentar hipoacusia y vértigo. Su diagnóstico requiere un examen físico completo que incluya otomicroscopía, audiometría ytomografía computada de ambos peñascos. El tratamiento depende de la sintomatología del paciente. En general, en un principio, es conservador, pero puede llegar a requerir cirugía. Se presenta un caso clínico de un niño de 6 años con fístula perilinfática secundaria a un traumatismo del oído izquierdo por un hisopo, que requirió tratamiento quirúrgico

Traumatic perilymphatic fistula is an unusual pathology. Generally caused by pencils, swabs, hair buckles, and matches. Among the most frequent symptoms, patients can present hearing loss and vertigo.Diagnosis requires a complete physical examination that includes otomicroscopy, audiometry and computed tomography of both boulders. Treatment depends on the patient's symptoms. In general, it is conservative at first, but may require surgery.We present a clinical case of a 6-year-old boy with perilymphatic fistula secondary to left ear trauma due to swab, which required surgical treatment

Absceso pulmonar con fístula neumocutánea / Pulmonary abscess with pneumocutaneous fistula

Lung abscess is a rare entity in pediatric age, but it generates significant morbidity. Even less frequent is the presence of this with spontaneous drainage to the skin, generating an abscess in the chest wall, reason for consultation, of the present clinical case. Subsequently, the presence of lung abscess with extension to the chest wall without pleural involvement was documented by imaging studies, an extremely rare and unusual entity, with only one case described in the world literature within our reach and in an adult patient.

El absceso pulmonar es una entidad infrecuente en la edad pediátrica, pero que genera una morbilidad importante. Aún menos frecuente es la presencia de este con drenaje espontáneo a piel, generando un absceso en pared torácica, motivo de consulta, del presente caso clínico. Posteriormente y por estudios imagenológicos se documentó la presencia de absceso pulmonar con extensión a pared torácica sin afectación pleural, una entidad extremadamente rara e inusual, con un solo caso descrito en la literatura mundial a nuestro alcance y en un paciente adulto.

Aspiration with or without lavage in the treatment of acute suppurative thyroiditis secondary to pyriform sinus fistula

ABSTRACT Objective There is currently no consensus regarding the optimal management of acute suppurative thyroiditis (AST) secondary to pyriform sinus fistula (PSF). To investigate the benefits and adverse events of aspiration with or without lavage for the treatment of AST secondary to PSF. Subjects and methods This was a retrospective analysis of consecutive patients with AST secondary to PSF who were admitted at the Affiliated Changzhou No. 2 People's Hospital of Nanjing Medical University between August 2012 and December 2018. Clinical information, procedural data, and imaging data were analyzed. Results Seven patients (five women; mean age, 16.9 ± 6.3 years; range, 8-26 years) were included. The patients most presented with anterior neck pain and swelling (n = 7), fever (n = 7), or odynophagia (n = 5). Six cases of AST occurred on the left side of the thyroid and 1 on the right. All patients had thyroid abscess. AST was diagnosed by ultrasound-guided needle aspiration cytology in all cases. PSF was diagnosed during the inflammatory stage in five patients and during the quiescent stage in two. All patients were treated with empiric antibiotics. Needle aspiration without lavage was performed in three cases. Needle aspiration with lavage was performed in four cases. Repeat aspiration was performed in three cases. All patients recovered completely, with no procedure-related complications. During 18.3 ± 7.8 months of follow-up, AST recurred in one case. Excision of the PSF was performed in another case. Conclusion Ultrasound-guided aspiration with or without lavage had a good treatment effect and without adverse events for the management of AST secondary to PSF.

Cholesteatoma labyrinthine fistula: prevalence and impact / Fístula labiríntica por colesteatoma: prevalência e impacto

Abstract Introduction: Labyrinthine fistula is one of the most common complications associated with cholesteatoma. It represents an erosive loss of the endochondral bone overlying the labyrinth. Reasons for cholesteatoma-induced labyrinthine fistula are still poorly understood. Objective: Evaluate patients with cholesteatoma, in order to identify possible risk factors or clinical findings associated with labyrinthine fistula. Secondary objectives were to determine the prevalence of labyrinthine fistula in the study cohort, to analyze the role of computed tomography and to describe the hearing results after surgery. Methods: This retrospective cohort study included patients with an acquired middle ear cholesteatoma in at least one ear with no prior surgery, who underwent audiometry and tomographic examination of the ears or surgery at our institution. Hearing results after surgery were analyzed according to the labyrinthine fistula classification and the employed technique. Results: We analyzed a total of 333 patients, of which 9 (2.7%) had labyrinthine fistula in the lateral semicircular canal. In 8 patients, the fistula was first identified on image studies and confirmed at surgery. In patients with posterior epitympanic and two-route cholesteatomas, the prevalence was 5.0%; and in cases with remaining cholesteatoma growth patterns, the prevalence was 0.6% (p = 0.16). In addition, the prevalence ratio for labyrinthine fistula between patients with and without vertigo was 2.1. Of patients without sensorineural hearing loss before surgery, 80.0% remained with the same bone conduction thresholds, whereas 20.0% progressed to profound hearing loss. Of patients with sensorineural hearing loss before surgery, 33.33% remained with the same hearing impairment, whereas 33.33% showed improvement of the bone conduction thresholds' Pure Tone Average. Conclusion: Labyrinthine fistula must be ruled out prior to ear surgery, particularly in cases of posterior epitympanic or two-route cholesteatoma. Computed tomography is a good diagnostic modality for lateral semicircular canal fistula. Sensorineural hearing loss can occur post-surgically, even in previously unaffected patients despite the technique employed.

Resumo Introdução: A fístula labiríntica é uma das complicações mais comuns associadas ao colesteatoma. Representa uma perda erosiva do osso endocondral que recobre o labirinto. As razões para a ocorrência da fístula labiríntica induzida pelo colesteatoma ainda são mal compreendidas. Objetivo: Avaliar pacientes com colesteatoma, a fim de identificar possíveis fatores de risco ou achados clínicos associados à fístula labiríntica. Os objetivos secundários foram determinar a prevalência de fístula labiríntica no estudo de coorte, analisar o papel da tomografia computadorizada e descrever os resultados auditivos após a cirurgia. Método: Este foi um estudo de coorte retrospectivo. Foram incluídos pacientes com colesteatoma adquirido de orelha média em pelo menos um lado sem cirurgia prévia que haviam sido submetidos à audiometria e tomografia computadorizada de orelha ou cirurgia em nossa instituição. Os resultados auditivos após a cirurgia foram analisados de acordo com a classificação de fístula labiríntica e da técnica empregada. Resultados: Analisamos um total de 333 pacientes, dos quais 9 (2,7%) apresentavam fístula labiríntica no canal semicircular lateral. Em 8 pacientes, a fístula foi identificada na tomografia computadorizada e confirmada durante a cirurgia. Em pacientes com colesteatomas epitimpânicos posteriores e de via dupla, a prevalência foi de 5,0%; e nos casos com padrão de crescimento de colesteatoma remanescente, a prevalência foi de 0,6% (p = 0,16). Além disso, a taxa de prevalência de fístula labiríntica entre pacientes com e sem vertigem foi de 2,1. Dos pacientes sem perda auditiva neurossensorial antes da cirurgia, 80,0% permaneceram com os mesmos limiares de condução óssea, enquanto 20,0% progrediram para perda auditiva profunda. Dos pacientes com perda auditiva neurossensorial antes da cirurgia, 33,33% permaneceram com a mesma deficiência auditiva, enquanto 33,33% apresentaram melhora da média de dos limiares de condução óssea aos tons puros. Conclusão: A fístula labiríntica deve ser descartada antes do procedimento cirúrgico, particularmente nos casos de colesteatomas epitimpânicos posteriores e de dupla via. A tomografia computadorizada é uma boa modalidade diagnóstica para a fístula do canal semicircular lateral. A perda auditiva neurossensorial pode ocorrer pós-cirurgicamente, mesmo em pacientes previamente não afetados, a despeito da técnica empregada.

Fístulas perianales: caracterización con resonancia magnética / Perianal fistulas: magnetic resonance classification

Las fístulas perianales constituyen una problemática frecuente en la consulta médica actual, con un gran impacto en la morbilidad. Su tratamiento no está exento de complicaciones, como la recurrencia local y la incontinencia fecal. La resonancia magnética (RM) cumple un rol fundamental en la planificación preoperatoria de estos casos, ya que la notable resolución espacial de los equipos de última generación permite generar un mapa de la anatomía de la pelvis menor, señalando el número y la relación de los trayectos con el esfínter anal. El objetivo del presente trabajo es identificar los distintos tipos de fístulas en base a sus características por RM, haciendo énfasis en la anatomía de la región y la técnica de estudio de esta entidad.

Perianal fistulas are a prevalent problem in current medical practice, with a high impact on morbidity. The treatment is not exempt from complications, such as local recurrence and faecal incontinence. Magnetic resonance imaging (MRI) performs an essential role insurgical planning of these patients, since the high spatial resolution of the latest equipment provides more precise information of the pelvis anatomy, indicating the number and relationship of the fistulous tracks with the anal sphincter. The aim of this work is to identify the different types of fistulas based on MRI classification, with particular emphasis on the local anatomy and study techniques.

The purpose of this paper is to report a congenital subclavian artery to subclavian vein fistula in a three weeks old male infant who presented with congestive heart failure and pulmonary hypertension. He had been scanned by various imaging modalities including echocardiography, cardiac computed tomography, diagnostic cardiac catheterization, cardiac magnetic resonance angiocardiography and cranial computed tomoangiography. He had successful surgical ligation after failure of device occlusion trial at age of 9 months.

Aortic root to left-atrial fistula after aortic valve replacement: A rare complication and its intraoperative management.

Aorto‑atrial fistula is a rare complication of prosthetic aortic valve replacement (AVR) and most of them have been diagnosed as a late complication. We present a case of this unusual complication after AVR. Intraoperative transoesophageal echocardiography identified and diagnosed this rare and potentially disastrous surgical complication and confirmed adequacy of its surgical repair.

Fístula laterocervical izquierda de tercer arco branquial: caso clínico / Third left laterocervical fistula gill arch: case report

En el presente trabajo queremos describir un caso poco común de trayecto fistuloso cervical. Se presenta en un nino y nos parece importante a tener en cuenta como diagnóstico diferencial, dentro de la otorrinolaringología infantil. Las anomalías branquiales pueden presentarse como quistes, trayectos sinusoidales o fístulas. Se explican por un mal desarrollo del arco branquial durante el periodo embriológico. Se presentan principalmente en la infancia entre los 2 a 3 años de edad y a veces también en la juventud. Aparecen igualmente en ambos sexos. Las fistulas del primer arco branquial son raras (1%-8%), las más comunes son las del segundo arco (90%). En nuestra experiencia el método de imagen de elección para evaluar las anomalías de los arcos branquiales es la fistulografia. El tratamiento de todas ellas es la exéresis quirúrgica.

In this paper we describe a rare case of cervical fistula tract. It comes in a child and it seems important to consider in the differential diagnosis, in ORL child. Branchial anomalies can present as cysts or fistulas sinusoidal paths. Explained by poor development of gill arch during embryologic. They occur mainly in children between 2-3 years of age and sometimes in youth. Appear equally in both sexes. The first brachial arch fistulas are rare (1%-8%>), the most common are the second arch (90%%). In our experience the imaging method of choice to evaluate abnormalities of the brachial arches is the sinogram. Treatment is surgical removal.

Imperforate Anus: Determination of Type Using Transperineal Ultrasonography

OBJECTIVE: This study was designed to assess the usefulness of transperineal ultrasonography (US) for the determination of imperforate anus (IA) type. MATERIALS AND METHODS:From January 2000 to December 2004, 46 of 193 patients with an IA underwent transperineal US prior to corrective surgery. Sonographic findings were reviewed to identify the presence of internal fistulas and to determine "distal rectal pouch to perineum (P-P)" distances. IA types were determined based on the sonographic findings, and the diagnostic accuracy of transperineal US was evaluated based on surgical findings. RESULTS: Of the 46 patients, 17 patients were surgically confirmed as having a high-type IA, three patients were confirmed as having an intermediate-type IA and 26 patients were confirmed as having a low-type IA. The IA type was correctly diagnosed by the use of transperineal US in 39 of the 46 patients (85%). In 14 of the 17 patients with a high-type IA, internal fistulas were correctly identified. All cases with a P-P distance > 16 mm were high-type IAs and all cases with a P-P distance < 5 mm were low-type IAs. CONCLUSION: Transperineal US is a good diagnostic modality for the identification of internal fistulas in cases of high-type IA and for defining the IA level.

Pyriform sinus fistula

Three patients had cervical draining sinus communicating with the pyriform sinus and one patient had acute suppurative thyroiditis resulting from infection through the pyriform sinus. There was a moderate to severe perithyroidal inflammation in all 4 cases. The age of onset ranged from 7 to 18 years old (mean; 12) but that of confirmation 9, 15, 18 and 67 years of age. Three of the patients were male and 3 of the cases involved the left side. All patients had suffered from several recurrences of cervical abscess, ranged from 2 to 7 times (mean; 4). Characteristic clinical features included 1) onset at a young age 2) frequent recurrence unless the fistula was extirpated completely 3) presenting with cervical draining sinus after repeated incision and drainage. It is supposed that the fistula is a route of infection mainly in the perithyroidal space and subsequently into the thyroid gland. When the fistula communicates directly with the thyroid gland, it can cause primary acute suppurative thyroiditis. Chronic cervical draining sinus with histories of repeated incision and drainage may be the clue to the diagnosis. A barium paste swallow study is the radiologic procedure of choice and complete removal of the fistula is the treatment of choice.

A case of pancreatico-colo-cutaneous fistula; management guided by endoscopic retrograde cholangio-pancreatography

A report of a 67-year-old man, who had been suffering from an enterocutaneous fistula after a left hemicolectomy due to colon cancer is presented. He had sudden intermittent upper abdominal pain and a high amylase level in the drainage fluid. The fistulogram showed a colocutaneous fistula with an abnormal cavity in the left upper quadrant. ERCP was performed to demonstrate the relationship between the pancreatic duct and the colocutaneous fistula connected with the abnormal cavity, and showed a pancreatico-colo fistula which was connected with the abnormal cavity. From the results of the above two studies, a diagnosis of the pancreatico-colocutaneous fistula could be drained, and a distal pancreatectomy, splenectomy and closing of the colonic opening were performed. After the operation, the patient was discharged without problem. We report herein a case of pancreaticocolocutaneous fistula which was confirmed by ERCP preoperatively and surgically treated successfully.
