Porphyria cutanea tarda (PCT) is a hereditary or acquired disease. It can be unleashed by iron overload, alcohol, estrogens and other conditions. In these patients, hepatic involvement can be associated to cirrhosis, iron overload or C and B viral infections, that are predisposing factors for hepatocellular carcinoma. We report a 69-year-old man with PTC, hemosiderosis and hepatocarcinoma. The tumor was diagnosed during a routine ultrasound examination for early detection of malignant lesions. The patient was subjected to a right hepatic excision. The pathological examination of the surgical piece confrmed the diagnosis and disclosed free surgical margins. After 18 months of follow up, the patient had a relapse and a liver transplantation was performed.

Background: Lipomas are frequent benign soft tissue tumors. They are classified as superficial or deep. In the head, they are localized under the galea or epicraneal aponeurosis. Clinically they present as non symptomatic smooth tumors. Aim: To describe ultrasound (US) findings of subgaleal lipomas. Material and methods: Retrospective review of seven patients aged between 31 and 52 years (five males) with subgaleal lipomas. Results: AH lipomas were localized in the forehead. At US, they appeared as solid masses; 43 percent were isoechoic and 47 percent hyperechoic compared to subcutaneous tissue. The average size was 13 mm. They had a semi spherical shape, with a flat base and a convex surface, a regular margin, no vascular vessels at Doppler ultrasound and were surrounded by the galea. Discussion: In this series of patients, all masses had a similar US appearance that suggested the diagnosis of lipoma.

Adenomyomatosis of the gallbladder wall is a frequent benign degenerative hyperplasia of unknown etiology. In some cases it looks like a malignant tumor. The diagnosis can be suspected during ultrasound examination. We report a 36 year-old male that presented with nonspecific dyspepsia. The ultrasound showed a gallbladder mass with small cyst and echogenic spot inside that suggested the presence of Rokitansky-Ashoff sinuses, seen in adenomyomatosis. The patient was operated and the tumor was excised. The pathological examination of the surgical specimen confirmed the presence of gallbladder adenomyomatosis.

La pancreatitis aguda es una entidad frecuente en nuestro medio. La enfermedad biliar es la causa principal en el desencadenamiento de ella. La evolución de la pancreatitis aguda puede adquirir diferentes formas clínicas que se relacionan con el pronóstico. Se proponen factores pronósticos de la enfermedad tanto desde el punto de vista clínico, de laboratorio y de imagenología. Se analizan los tratamientos actuales y conductas terapéuticas

During workshop, hepatologists analyzed and gave recomendations about gallbladder polyps. They arrived to the following agreements: gallbladder polyps of less than 10 mm should be followed with ultrasonography at 3, 6 and 12 months if there is no enlargement. If there is enlargement, a cholecystectomy should be performed. Polyps larger than 10 mm should be subjected to cholecystectomy

En nuestro medio, la coledocolitiasis es una de las causas más frecuentes de obstrucción de la vía biliar. Sin embargo, es necesario precisar el diagnóstico preoperatorio dado que las otras causas de colestasis extrahepática tienen pronóstico y tratamiento diferentes. Se evaluó el rendimiento (sensibilidad y especificidad) de la ecotomografía en el diagnóstico de la coledocolitisis en 115 casos, 78 con esta patología comprobada por colangiografía transparietohepática y corroborada por operación. Los 37 casos restantes son el grupo control en los que la colangiografía transparietohepática y la evolución clínica demostraron la normalidad de la vía biliar principal. La sensibilidad de la ecotomografía para hacer el diagnóstico de obstrucción biliar fue 0,87 y su especificidad 0,65 y para demostrar la coledocolitiasis de 0,47 y 1,00 respectivamente, con una prevalencia de coledocolitiasis de 0,68 en el grupo analizado. Dado el rápido desarrollo tecnológico experimentado por la ecotomografía y la incorporación de un variado y numeroso grupo de observadores, es posible esperar una variación significativa de su rendimiento. De los 78 casos de coledocolitiasis estudiados, 61 tenían ecotomografías hechas en nuestro Servicio y 17 realizadas fuera del Hospital. En el primer grupo, la ecotomografía demostró dilatación de la vía biliar en 56 casos (91,8%) y coledocolitiasis en 34 (55,7%), mientras que en el segundo, estas cifras fueron de 12 (70,6%) y 3 (17,6%) respectivamente. Por lo tanto, en nuestro Hospital, la sensibilidad de la ecotomografía para hacer el diagnóstico de obstrucción biliar y de coledocolitiasis fue de 0,92 y 0,56 y su especificidad de 0,65 y 1,00 respectivamente
