Diagnóstico prenatal de quistes interhemisféricos asociados a agenesia del cuerpo calloso / Prenatal diagnosis of callosal agenesis with interhemispheric cyst

Introducción: Los quistes interhemisféricos asociados a agenesia del cuerpo calloso constituyen un grupo infrecuente y heterogéneo de anomalías del SNC. Objetivo: Reportar nuestra experiencia en quistes interhemisféricos asociados a agenesia del cuerpo calloso (QIH/ACC), haciendo énfasis en sus características en la neurosonografía (NSG), su comparación con la resonancia magnética (RM) y su evolución clínica posterior. Método: Se incluyeron todas las pacientes con QIH/ACC evaluadas desde el año 2008. En todos los casos se consignaron los datos clínicos, de NSG y de RM cuando se realizó. Se entrevistó telefónicamente a los padres. Resultados: Fueron seleccionados 9 casos con QIH/ACC. De ellos, 5 fueron quistes tipo 1, 3 tuvieron anomalías asociadas y en los 3 hubo una anomalía genética patogénica. Cuatro casos fueron quistes tipo 2, 3 de ellos con un patrón NSG sugerente de síndrome de Aicardi. Hubo una excelente correlación entre NSG y RM, ya fuera esta última realizada ante- o posnatal, particularmente con relación a las malformaciones del desarrollo cortical asociadas al QIH/ACC. Conclusiones: En comparación con la RM y el resultado final, hubo alta concordancia con lo diagnosticado en la NSG, en especial en cuanto a malformaciones del desarrollo cortical asociadas, lo que añade valor al método diagnóstico que ofrecemos a nuestra población consultante.

Background: Callosal agenesis associated with interhemispheric cysts correspond to a rare and heterogenous group of CNS anomalies. Objective: To report our experience in interhemispheric cysts associated with agenesis of the corpus callosum (QIH/ACC), emphasizing its characteristics in neurosonography (NSG), its comparison with magnetic resonance imaging (MRI) and its subsequent clinical evolution. Method: All patients with QIH/ACC evaluated since 2008 were included. In all cases, clinical, NSG and MRI data were recorded when performed. The parents were interviewed by telephone. Results: A total of 9 cases were selected with QIH/ACC. 5 cases were type 1 cysts, 3 of them had associated abnormalities and in all 3 there was a pathogenic genetic anomaly. 4 cases were type 2 cysts, 3 of them with an NSG pattern suggestive of Aicardi syndrome. There was an excellent correlation between NSG and MRI, either before or postnatally, particularly in relation to cortical developmental malformations associated with QIH/ACC. Conclusions: Compared to MRI and the final result, there was high agreement with what was diagnosed in NSG, especially in what corresponds to associated cortical developmental malformations, which adds value to the diagnostic method we offer to our consulting population.

Ascitis pancreática traumática, manejo conservador: reporte de un caso / Post-traumatic pancreatic ascites, conservative management: a case

Resumen Objetivo: Presentar el caso de un paciente masculino adulto joven, con ascitis pancreática secundaria a lesión del conducto pancreático por trauma abdominal cerrado, tratado con éxito con terapia conservadora. Materiales y Método: Datos e imágenes recopilados de la historia clínica del Hospital Universitario de Santander, previo consentimiento informado. Resultados: Sexo masculino de 21 años con antecedente de trauma abdominal cerrado, quien consulta por distensión, dolor abdominal progresivo y pérdida de peso no cuantificada. Ante sospecha de lesión de conducto pancreático se solicitó pancreatografía por resonancia magnética que evidencia una alteración del segmento proximal del conducto pancreático principal asociado a lesión quística en el borde anterior de la unión de la cabeza con el cuerpo pancreático. Se decidió manejo conservador por 4 semanas con colocación de dren abdominal, reposo intestinal, asociado a nutrición parenteral total y análogos de somatostatina. Discusión: Un 5% del trauma abdominal cerrado puede provocar pancreatitis y fugas en el conducto pancreático. Conclusión: La lesión del conducto pancreático principal debe sospecharse en todos los pacientes con trauma abdominal cerrado. El manejo debe realizarse con una planificación cuidadosa y exhaustiva.

Aim: To present the case of a young adult male patient, with pancreatic ascites secondary to pancreatic duct injury due to blunt abdominal trauma, treated successfully with conservative therapy. Materials and Method: Data and images were obtained from the clinical chart of the "Hospital Universitario de Santander" with prior informed consent. Results: 21-year-old male patient with a blunt abdominal trauma background, who consulted for distension, progressive abdominal pain, and subjective weight loss. Due to suspicion of a pancreatic duct injury, a magnetic resonance cholangiopancreatography was requested, which showed an alteration of the proximal segment of the main pancreatic duct associated with a cystic lesion at the anterior border of the junction between the pancreatic head and body. Treatment consisted of a 4-week conservative therapy with the placement of an abdominal drain, bowel rest, associated with total parenteral nutrition and somatostatin analogs. Discussion: A 5% of blunt abdominal trauma can cause pancreatitis and pancreatic duct leaks. Conclusión: Pancreatic duct injury should be suspected in every patient with blunt abdominal trauma. Management must be done with careful and thorough planning.

Iris cyst and atypical complications / Cisto de íris e complicações atípicas

ABSTRACT The authors report the case of a male adult presenting significant ocular complications and irreversible visual impairment, resulting from the long-term progression and late diagnosis of an iris cyst in the right eye, probably secondary to trauma. The patient was admitted to Hospital Universitário Antonio Pedro with a total corneal opacity that blocked direct visualization of the anterior chamber. Ultrasound biomicroscopy was crucial for the anatomic study, and the patient was submitted to enucleation for aesthetic improvement and clarifying diagnosis. We concluded athalamia and deformation of the anterior segment, due to expansion of the cyst, led to gradual elevation of the intraocular pressure and damage of the optic nerve, resulting in visual loss.

RESUMO Relatamos o caso de um paciente com evolução e diagnóstico tardios de cisto de íris no olho direito, provavelmente secundário a trauma, com complicações importantes e baixa irreversível da visão, tendo sido admitido no Hospital Universitário Antônio Pedro já com leucoma total da córnea e câmara anterior indevassável. A biomicroscopia ultrassônica se mostrou imprescindível para o estudo anatômico, sendo o paciente finalmente submetido à enucleação, para melhora estética e elucidação diagnóstica. Concluímos que a atalamia e a desestruturação do segmento anterior, consequentes ao crescimento cístico, levaram a um gradativo aumento da pressão intraocular e lesão do nervo óptico, com consequente perda da visão.

Tortícolis como forma de presentación de quiste de la bolsa de Blake. Diagnóstico ecográfico en atención primaria / Torticolis as a form of presentation of Blake's pouch cyst. Ultrasound diagnosis in primary care

La tortícolis es un signo clínico definido por la inclinación lateral del cuello y rotación de la cabeza, que puede ser fija o flexible y acompañarse o no de dolor cervical. Aparece en trastornos de diferente complejidad. Ante un caso de tortícolis, es preciso realizar una historia clínica cuidadosa y un examen físico completo, y, en caso de ser persistente, solicitar pruebas de imagen.Se hace referencia a una causa de tortícolis no descrita en la literatura. Se trata de una tumoración quística compresiva en la fosa craneal posterior, quiste de la bolsa de Blake, en una lactante pequeña diagnosticada mediante ecografía en la consulta de Pediatría de Atención Primaria. Tras el diagnóstico, se remitió al centro hospitalario de referencia, donde se intervino de urgencia por Neurocirugía Pediátrica, mediante fenestración de la tumoración por ventriculostomía endoscópica y derivación ventrículo-peritoneal. Actualmente, se encuentra asintomática y sin secuelas.

Torticollis is a clinical sign defined by the lateral inclination of the neck and rotation of the head, which can be fixed or flexible and accompanied or not by cervical pain. It appears in disorders of different complexity. In a case of torticollis it is necessary to carry out a careful medical history and a complete physical examination and, if persistent, request imaging tests.Reference is made to a cause of torticollis not described in the literature. This is a compressive cystic tumor in the posterior cranial fossa, Blake's pouch cyst, in a small infant diagnosed by ultrasound in the Primary Care Pediatrics office. After diagnosis, she was referred to the referral hospital, where emergency intervention was performed by pediatric neurosurgery, by fenestration of the tumor by endoscopic ventriculostomy and ventriculo-peritoneal shunt. She is currently asymptomatic and without sequelae.

Tailgut cyst adenocarcinoma

Tailgut cysts (TGCs) are rare congenital entities arising from remnants of the embryological postanal primitive gut. Malignancy in TGCs is rare, with the majority being adenocarcinomas and carcinoid tumors. A search of the published literature yielded only 27 cases of adenocarcinoma developing in TGCs. We described the case of a 54-year-old female who presented with complaints of pelvic and perineal pain of several weeks. After the initial work-up, a mass in the right presacral location was diagnosed. She underwent radical resection of the tumor, using a posterior approach. The lesion was removed en bloc with the middle rectum, coccyx, and sacrum (S4­S5). The histopathologic examination revealed an adenocarcinoma arising in a TGC, and the patient received adjuvant chemoradiotherapy. Our case underlines that diagnosing a TGC is difficult as it is a rare congenital lesion. Clinical examination may be challenging as TGCs present with various symptoms, which can mimic other commonly proctologic disorders. Patients should be referred to a tertiary center with experience in pelvic surgery and must be managed by a multidisciplinary approach to maximize successful treatment. The recommended treatment is surgical excision given the malignant potential of TGCs and their risk of causing local complications.

Enfrentamiento a una masa cervical no tiroidea en Atención Primaria / Confrontation with a non-thyroid cervical mass in Primary Care

The clinical approach to non-thyroid cervical masses in primary care has always been considered a diagnostic challenge. In the absence of specific diagnostic methods, the general practitioner must rely on clinic and general tests in order to achieve a suspected diagnosis and timely referral. On initial approach to cervical masses, one must first analyze each case according to patient age, associating an exhaustive anamnesis focused on the growth pattern and aggregate symptoms, along with a physical examination focused on signs of malignancy. Once completed, the etiology of the mass can be classified as probable congenital, inflammatory or tumoral origin. And also try to determine localization, temporality and discriminate between benign and malignant causes. Once the clinical interrogation has been completed, basic complementary tests and/or directed test according to suspicion can be requested. The foregoing allows the primary care physician a proper referral to specialist and/or initiation of appropriate treatment. (AU)

Manejo quirúrgico del quiste adrenal gigante: reporte de caso y revisión de la literatura / Surgical management of giant adrenal cyst: case report and review of the literature

OBJETIVO: Presentar un caso de quiste adrenal (QA) gigante resecado por vía mínimamente invasiva y realizar una revisión narrativa de la literatura disponible al respecto. MATERIALES Y MÉTODOS: Se presenta el caso de un paciente de sexo masculino de 54 años, con una masa retroperitoneal izquierda de crecimiento lento, asintomático, con imágenes y biopsia sugiriendo un QA complejo con sospecha de infiltración renal. Se indica una resección laparoscópica transabdominal. RESULTADOS: Se encuentra como hallazgo intraoperatorio un QA complejo hemorrágico de 9 cm de diámetro, con adherencia a la fascia de Gerota izquierda, logrando exéresis completa del QA por mínima invasión. El paciente evolucionó satisfactoriamente y fue dado de alta al segundo día posoperatorio. Es asintomático en 19 meses de seguimiento. Si bien los QA son benignos, los QA gigantes con crecimiento rápido, sintomáticos o de conversión hemorrágica, pueden ser resecados por adrenalectomía laparoscópica sin aumento de morbimortalidad. DISCUSIÓN: El abordaje laparoscópico de los QA no funcionales gigantes debe ser considerado como el manejo de elección. Es necesaria más evidencia sobre resultados en diferentes abordajes para generar recomendaciones claras. CONCLUSIÓN: Este reporte se suma a la evidencia actual en cuanto al abordaje mínimamente invasivo para QA gigantes hemorrágicos.

OBJECTIVE: Present a giant adrenal cyst (AC) case treated with minimally invasive resection and to perform a narrative literature review available. MATERIAL AND METHODS: A 54 year-old male presents with a left retroperitoneal slow growing mass, no symptoms, with a complex AC evidenced by previous images and mass biopsy, with suspected renal infiltration. A transabdominal laparoscopic resection is indicated. RESULTS: A complex hemorrhagic 9 cm diameter AC was found, with adhesions to left Gerota's fascia. Complete resection of the AC was achieved through minimally invasive approach. The patient had an uneventful clinical recovery and was discharged on the second postoperative day. On 19th month of follow-up is completely asymptomatic. Even though the AC are benign lesions, the symptomatic giant AC, with fast growing ratio, and/or hemorrhagic conversion could be resected though laparoscopic adrenalectomy, with no increased morbidity or mortality. DISCUSSION: The laparoscopic approach for giant non-functional AC should be considered as the standard of care. More evidence is required in terms of surgical approach outcomes to define clear recommendations. CONCLUSION: This report adds to the actual evidence in terms of minimally invasive approach for hemorrhagic giant AC.

Paratracheal cyst rupture: a differential diagnosis for tracheal rupture / Ruptura de cisto paratraqueal: um diagnóstico diferencial para ruptura traqueal

Abstract Tracheobronchial rupture is a rare but potentially life-threatening complication commonly caused by neck and chest trauma. Iatrogenic tracheobronchial rupture can be caused by intubation, tracheostomy, bronchoscopy but also linked to pre-existing primary diseases. Paratracheal air cysts, infrequently described in literature, seem to be associated with obstructive lung disease and weaknesses in right posterior lateral wall of the trachea. We report a case of a paratracheal air cyst rupture in a previous healthy patient.

Resumo A ruptura traqueobrônquica (RTB) é uma complicação rara, mas potencialmente fatal, comumente causada por trauma de pescoço e tórax. A RTB iatrogênica pode ser causada por intubação, traqueostomia, broncoscopia, mas também pode estar relacionada a doenças primárias preexistentes. Os cistos aéreos paratraqueais, raramente descritos na literatura, parecem estar associados à doença pulmonar obstrutiva e fraqueza da parede posterolateral direita da traqueia. Relatamos o caso de uma ruptura de cisto aéreo paratraqueal em paciente previamente saudável.

Estridores laríngeos supraglóticos / Supraglottic laryngeal stridors / Estridores laríngeos supraglóticos

Toda obstrucción de la vía aérea se expresa por un estridor que será diferente según la localización de la obstrucción. El estridor es un ruido ocasionado por el pasaje de aire en forma turbulenta a través de una vía aérea con calibre disminuido. Cuando la obstrucción se ubica por encima de las cuerdas vocales el estridor será inspiratorio. Describimos diferentes patologías de la laringe supraglótica, congénitas y adquiridas, que presentan estridor en algún momento de su evolución.

An obstructed airway causes stridor. Stridor willbe different depending on the location of the obstruction. Stridor is a noise caused by the passage ofturbulent air through a diminished airway caliber. If the obstruction occurs above the vocal cords, itwill be inspiratory. We describe different pathologies of the supraglotticlarynx, both congenital and acquired, producingstridor at some moment of their evolution.

Uma via aérea obstruída provoca estridor. Estridor será diferente dependendo da localização da obstrução. Estridor é um ruído causado pela passagemdo ar turbulento através de uma diminuição do calibre das vias aéreas. Nós descrevemos diferentes patologias da laringe supraglótica, tanto congênitas e adquiridas, que apresentam stridor em algum momento de sua evolução.

Large thyroid cyst in a patient with congenital hypothyroidism / Grande cisto tiroidiano em paciente com hipotireoidismo congênito

Thyroid hormone biosynthetic defects are rare causes of congenital hypothyroidism. Although, initial presentations are usually diffuse goiter and hypothyroidism, subsequently they may develop thyroid nodules and or thyroid cancer. We describe a case of hypothyroidism due to dyshormonogenesis whose one of the previously solid nodules degenerates into a large cyst. A 22-year-old male was referred to our clinic for evaluation of enlarging thyroid nodule. Hypothyroidism was diagnosed in infancy, however due to poor compliance to treatment TSH values were elevated most of the times. When he was fifteen the first nodule was detected which was a solid cold nodule. Fine needle aspiration was in favor of benign follicular nodule. Seven years later we found a large multi nodular thyroid with a predominant large cyst corresponding to the previously detected solid nodule. 21cc straw colored fluid was aspirated. Cytology was reported as benign cystic nodule. The patient underwent thyroidectomy and pathology confirmed a benign thyroid cyst. Although underreported thyroid dyshormonogenesis may progress to cystic degeneration. Taking into account the risk of malignancy and eventually cyst formation, we recommend more frequent evaluation in the face of nodule formation in these patients.

Os defeitos de biossíntese do hormônio tiroidiano são causas raras de hipotireoidismo congênito. Embora as apresentações iniciais sejam geralmente bócio difuso e hipotireoidismo, nódulos tiroidianos ou câncer de tiroide podem se desenvolver subsequentemente. Descrevemos aqui um caso de hipotireoidismo causado por disormonogênese e no qual um dos nódulos sólidos degenerou em um grande cisto. Um homem de 22 anos de idade foi encaminhado para nossa clínica para avaliação do aumento de um nódulo tiroidiano. O hipotireoidismo foi diagnosticado na infância. Entretanto, em razão da baixa conformidade ao tratamento, os valores de TSH estavam elevados na maior parte do tempo. Quando o paciente tinha 15 anos de idade, um primeiro nódulo sólido e frio foi detectado. A aspiração por agulha fina mostrou um nódulo folicular benigno. Sete anos depois encontramos múltiplos nódulos na tiroide e um grande cisto predominante que correspondia ao nódulo sólido anteriormente detectado. Foram aspirados 21cc de fluido cor de palha. A citologia mostrou um nódulo cístico benigno. O paciente foi submetido à tiroidectomia e o exame histopatológico confirmou um cisto tiroidiano benigno. Embora não seja comumente relatada, a disormonogênese da tiroide pode progredir para a degeneração cística. Ao serem considerados o risco de malignidade e a eventual formação de cistos, recomendamos uma avaliação mais frequente da formação de nódulos nesses pacientes. Arq Bras Endocrinol Metab. 2014;58(9):958-61.

Some of cases which is very confusing in regards either it is benign or malignant, the computed tomography is more sensitive.

Monosegmental Hepatobiliary Fibropolycystic Disease Mimicking a Mass: Report of Three Cases

Hepatobiliary fibropolycystic diseases are a unique group of entities involving the liver and biliary tract, which are caused by abnormal embryologic development of the ductal plates at various stages. We experienced strange hepatobiliary fibropolycystic diseases with a complex mass composed of malformed ducts and biliary cysts, which did not belong to, and were different from, previously known malformations. They were unique in imaging and histologic features. We herein report three cases of monosegmental hepatobiliary fibropolycystic disease mimicking a mass.
