Small bowel masses due to gallstones: report of two cases

Two patients are described with solitary small bowel masses due to gallstones. Radiographs showed evidence of choledocho-duodenal fistula formation. Even when a study with contrast medium is intended primarily for the examination of the small intestine, a solitary intraluminal mass should direct attention to the duodenal loop where evidence of a fistula should be sought.
