Fluoroscopic findings in Bouveret syndrome.

Bouveret syndrome occurs when a gallstone passes into the duodenum from a fistulous communication between the gallbladder and the duodenum. This is an uncommon cause of abdominal pain which is often diagnosed following surgery. Most imaging findings of Bouveret syndrome are limited to computed tomography.

Liver fluke-induced choledocholithiasis with biliary ductal obstruction.

Liver fluke-related biliary disease is rare in the United States, as locally-acquired liver fluke infection is uncommon. Presented here is a case of biliary obstruction secondary to fluke infection in a Burmese immigrant to the United States. Imaging findings are presented using computed tomography, ultrasound, magnetic resonance imaging, and fluoroscopy which revealed severe biliary dilatation resulting from large obstructing stones.

Spectrum of Xanthogranulomatous Processes in the Abdomen and Pelvis: A Pictorial Review of Infectious, Inflammatory, and Proliferative Responses.

Objective: Xanthogranulomatous (XG) processes are rare inflammatory conditions with the characteristic pathologic feature of lipid-laden macrophages or histiocyte cells. Imaging findings are nonspecific and can simulate aggressive neoplastic processes. XG processes can be caused by infection, inflammation, histolytic process, or an inherited lysosomal disorder.
