RESUMO
Background The ventriculoperitoneal shunt (VPS) procedure is still themost used technique for management of hydrocephalus. This article reports a case of hepatic cerebrospinal fluid (CSF) pseudocyst as a rare, but important, complication of the VPS insertion. Case Description An 18-year-old male presented to the hospital complaining of temporal headache and visual turbidity for approximately 3 months with a history of VPS insertion for treatment of hydrocephalus and revision of the valve in adolescence. The diagnosis was based on abdominal imaging, demonstrating an extra-axial hepatic CSF pseudocyst free from infection. Following the diagnosis, the management of the case consisted in the removal and repositioning of the catheter on the opposite site of the peritoneum. Conclusion The hepatic CSF pseudocyst is an infrequent complication of VPS procedure, but it needs to be considered when performing the first evaluation of the patient. Several techniques are considered efficient for the management of this condition, the choice must be made based on the variables of each individual case.

Introducción: Quistes hepáticos son formaciones de contenido líquido-seroso rodeado de parénquima hepático normal y sin comunicación con la vía biliar intrahepática. Mayor incidencia en adultos mayores de 50 años, con una relación mujer / hombre de 1.5: 1. Son asintomáticos. Los síntomas se presentan debido a su tamaño o bien por la presencia de complicaciones como la hemorragia, la rotura, la infección intraquística, o la compresión de estructuras adyacentes. Objetivo: Caracterizar a una paciente que presenta quiste hepático gigante complicado por rotura traumática. Caso clínico: Paciente femenino de 81 años, acudió a emergencia luego de haber presentado caída impactándose sobre superficie dura a nivel de parrilla costal e hipocondrio derecho, presentó dolor abdominal intenso acompañado de nausea y vómito. Al examen físico mostró signos claros de irritación peritoneal. Se realizó tomografía axial computarizada que reporta rotura de la pared de quiste hepático y aproximadamente 600 ml de líquido libre en cavidad. Se efectúo tratamiento quirúrgico de emergencia al realizar destechamiento del quiste y lavado de la cavidad. Conclusiones: Los quistes hepáticos, debido a su tamaño o complicaciones pueden poner en peligro la vida de los pacientes. Es necesario que dentro del arsenal diagnóstico del cirujano esté presente el conocimiento de esta patología(AU)
Introduction: Hepatic cysts are formations with liquid-serous content surrounded by normal liver parenchyma and without communication with the intrahepatic bile duct. It is reported with higher incidence in adults over fifty years of age, with a women/men ratio of 1.5: 1. They are asymptomatic; symptoms appear due to either their size or the presence of complications such as hemorrhage, rupture, intracystic infection, or compression of adjacent structures. Objective: To characterize a patient with a giant hepatic cyst complicated by traumatic rupture. Clinical case: A 81-year-old female patient went to the emergency room after falling and subsequently impacting herself on a hard surface at the level of the rib cage and right hypochondrium; she presented intense abdominal pain accompanied by nausea and vomiting. The physical examination showed clear signs of peritoneal irritation. A computerized axial tomography was performed, reporting rupture of the hepatic cyst wall and approximately 600 mL of free fluid within the cavity. Emergency surgical treatment was performed after cyst unroofing and cavity washing. Conclusions: Hepatic cysts, due to their size or complications, can endanger the patients' lives. It is necessary for the surgeon to consider knowledge of this condition as part of his or her diagnostic resources(AU)

INTRODUCTION: Congenital hepatic cyst is a rare hepatobiliary malformation that can present as an asymptomatic, unilocular, upper abdominal cystic mass in the fetus. CASES: We report two cases of congenital hepatic cyst in which the diagnosis was made by prenatal ultrasound at 25 and 33 weeks' gestation. The diagnosis was confirmed postnatally by abdominal ultrasound and radiologic imaging studies. Although the infants remained asymptomatic, laparoscopic excision was performed due to the increasing size of the cyst in both cases. Pathological examination of the resected specimens confirmed a simple cyst in one case and an epidermoid cyst in the other. CONCLUSIONS: Our cases and those described in the literature demonstrate the usefulness of incidental prenatal detection of congenital hepatic cyst, especially during late pregnancy. Such a diagnosis can allow for proper perinatal surveillance, selection of the route of delivery, and timely postnatal surgical intervention if required.
RESUMO
A female patient, 59-year-old, was complaining of abdominal pain in the right hypochondrium and mesogastrium for 6 months. Ultrasonography and abdominal computed tomography were performed, both confirming a large hepatic cyst (10.6 cm × 7.6 cm × 7.3 cm) on the left lobe. A hybrid minilaparoscopic resection was proposed. We opted for unroofing the cyst, and the procedure was uneventfully performed, with a total surgical time of 60 min. In the post-operative the patient did well, with minimal abdominal pain, being discharged on the 5th post-operative day, after drain removal due to the use of intravenous antibiotic therapy.
RESUMO
We describe a minimally invasive alternative approach in a patient with infected hepatic cyst to stabilize the patient before definitive surgery. A 58-year-old man presented with fever and hypotension after 2 weeks of asthenia, chills, weight loss, slight abdominal pain, and a previous asymptomatic simple hepatic cyst. On ultrasound, a giant heterogeneous hepatic cyst with thick wall was noted. A positron emission tomography-computed tomography scan was indicated and demonstrated high uptake (standardized uptake value = 7.6) in the wall of the cyst, suggestive of infection. He underwent percutaneous drainage guided by the tomography. A 12 Fr drain was positioned inside the collection and 5 L of purulent material was aspirated from the cyst, and at day 12th, surgical resection was performed. Histopatological analysis confirmed a simple biliary cyst. The patient remains asymptomatic on 1-year follow-up. Percutaneous drainage before surgical treatment allowed the definitive approach to be performed with the patient in better clinical conditions.

El hamartoma mesenquimatoso hepático es un tumor benigno poco frecuente, formado por alteraciones de la placa hiliar y compuesto por tejidos mixomatoso, mesenquimático y conductos biliares anormales en proporciones variables. Habitualmente son formaciones hepáticas múltiples, quísticas y sin comunicación con la vía biliar. Es más frecuente en niños, es raro en adultos. El primer caso fue publicado por Yamamura et al en 1976, y se encuentran pocos en la bibliografía. Presentamos el caso de un paciente de 87 años con un hamartoma hepático quístico de 20 cm.
The mesenchymal hamartoma of the liver is a non frequent benign tumor with a ductal plate malformation, consisting of myxoid mesenchymal tissue and abnormal bile ducts in different proportion. Usually it presents as multiple liver cyst formations without communication with the principal bile duct. They are frequent in children, being rare in adults. The first case was reported by Yamamura et al in 1976, and very few cases are reported in the bibliography. We present the case of an elder 87 year old male who presented a 20 cm mesenchymal hamartoma liver cyst.

INTRODUÇÃO: Pesquisa de corpo inteiro após dose terapêutica de (131I) NaI (PCI) associada à tireoglobulina (Tg) sérica, anticorpo antitireoglobulina (anti-Tg) e ultrassom (US) cervical representam os métodos de referência para detecção de carcinoma diferenciado de tireoide (CDT) residual ou metastático. Algumas causas de PCI falsos-positivas, como processos inflamatórios, alguns tumores não tireoidianos e até mesmo cistos renais e sebáceos, são bem conhecidas. MÉTODOS: Neste trabalho, descreveu-se um caso de cisto hepático benigno simulando metástase de carcinoma de tireoide em PCI após dose terapêutica de (131I) NaI. RESULTADOS: Ressalta-se a importância do reconhecimento dos cistos hepáticos benignos como fator complicador do seguimento dos pacientes com câncer de tireoide. CONCLUSÕES: Para minimizar erros de diagnóstico e, consequentemente, na condução dos casos de CDT, é necessário conhecer as possíveis causas de PCI falsos-negativas e positivas.
INTRODUCTION: The follow-up of differentiated thyroid carcinoma (DTC) for detecting persistent or recurrent disease is based on iodine whole body scan (WBS), the evaluation of the tumor marker thyroglobulin (Tg), the anti-thyroglobulin antibody (anti-Tg) and neck ultrasonography (US). Well known false-positive causes of WBS include inflammatory processes, some non-thyroid tumors, kidney or even sebaceous cysts . METHODS: We reported a case of false-positive WBS, after therapeutic dose of (131I) NaI. RESULTS: We enphasize the importance of recognizing benign liver cysts mimicking DTC metastasis. CONCLUSIONS: False-positive and negative results may occur with WBS and must be recognized to avoid mismanagement.
