A CT scan of the abdomen and pelvis showed gallstone-induced inflammatory changes about the duodenum consistent with duodenitis as well as the presence of pneumobilia (Figure 1).
3,18) In a series of 64 cases of Bouveret syndrome in which abdominal radiographs were conducted, Cappell and Davis reported the discovery of pneumobilia in 39%, a dilated stomach in 23%, and dilated loops of bowel in 14% of cases.
Diagnostic ultrasound scans usually depict what is known as a "double-arch sign" which can arouse suspicion particularly if pneumobilia is seen as well.
Because of the relative lack of specificity with plain abdominal radiographs and ultrasound for a bilioenteric fistula, one should also remain cognizant of other common causes of pneumobilia (Table 2).
Pneumobilia is well recognised in adults in the context of gallstone ileus and after endoscopy.
The classic radiographic signs of gallstone ileus, described in 1941 by Rigler et al, are pneumobilia, mechanical small-bowel obstruction, and the presence of a new stone or changed position of a previously identified stone (2).
The only positive finding on CT scan was pneumobilia, most likely due to sphincterotomy during the ERCP.
An external biliary drain with pneumobilia was noted.
The replacement of the common bile duct stent with interval development of intrahepatic pneumobilia was also noted.
