ABSTRACT
A case of histologically proven carcinosarcoma arising in the extrahepatic biliary tree is presented. The tumor appeared on cholangiography and computed tomography as a large expansile intraluminal mass causing biliary obstruction.

In its early stages, septic cavernous sinus thrombosis may be difficult to differentiate from orbital cellulitis. We describe a case in which digital subtraction orbital venography proved to be a superior technique for clarifying this clinical dilemma, and we stress the clinical importance of making this differentiation.

Multiple myeloma with extramedullary plasmacytoma is unusual, but associated gastrointestinal involvement is even rarer. A case with initial presentation as solitary plasmacytoma of the clavicle and subsequent lesions in the maxillary sinus, skin, and ascending colon is reviewed. The variable radiographic features of plasmacytoma of the colon are discussed, whether occurring as a solitary finding or in a patient with multiple myeloma.
