| pubmed-article:16362271 | pubmed:abstractText | Ectopic gallstone obstruction, gallstone ileus, due to cholecystoenteric fistula is an infrequent condition. Its occurrence as a complication of a gallbladder (GB) carcinoma is even more rare. We describe an unusual case of a GB carcinoma complicated by a cholecystoduodenal fistula leading to first gallstone obstruction in the ileum and then, later, in the duodenum, in which an accurate preoperative diagnosis was based on pathognomonic computerized tomography (CT) features. A correct diagnosis of this may be crucial and requires prompt surgical intervention; radiologists should be familiar with their classic CT appearance. | lld:pubmed |
