RESUMO
The first communication on biliary complications secondary to a portal cavernoma was published in 1965 [Br. J. Surg. 52 (1965) 636.], and since then several cases have been reported in the medical literature. These biliary complications, studied initially by anterograde or retrograde cholangiography, and later MR cholangiography [Van Hoe L, Van Beckevoort D, Van Steenbergen W. Atlas of across-sectional and projective MR cholangiography. Berlin: Springer; 1999. p. 166-7.], appear to be secondary to a double mechanism which produces a compression of the common bile duct (CBD) and ischemic changes. The biliary abnormalities most frequently found are a dilatation of the intrahepatic biliary ducts associated with extrinsic strictures and segmental dilatation of the CBD [J. Radiol. 83 (2001) 341.]. We report a rare type of portal cavernoma characterized by a thickening of the walls of the CBD and by a dilatation of the intrahepatic biliary ducts. The thickened walls of the CBD were evaluated by ultrasound and by magnetic resonance imaging.

Reported is a new case of a Kaposi's sarcoma involving only the colorectal area in an HIV-negative patient presenting with hemorrhagic rectocolitis. The colonoscopic examination and the radiological imaging showed the presence of multiple nodular pseudopolypoid formations in the rectum, which suggested, in the differential diagnosis, primarily a malignant non-Hodgkin lymphoma.
