The differential diagnosis of Chilaiditi's syndrome includes pneumoperitoneum, pneumobilia
, and hepatic-portal venous gas.
is a common finding and is due to either the reflux of enteric gas from stone passage across the ampulla or due to infection with gas-forming organisms.
The addition of T1-weighted gradient echo in phase images to standard MRCP sequences improves the detection and differentiation of hepatolithiasis and intrahepatic pneumobilia
In a patient with gallstone ileus, imaging studies typically show a classic radiographic triad (Rigler's triad) consisting of small bowel obstruction, pneumobilia
, and an ectopic gallstone.
The classic Riglers triad of radiography includes mechanical bowel obstruction pneumobilia
and an ectopic gallstone within bowel lumen.
A repeat ultrasound scan showed pneumobilia
with no biliary dilatation or mass.
Enlarged biliary ducts with thickened walls in the left hepatic lobe, and hyperechoic biliary ducts with posterior reverberation in the right lobe--suggestive for cholangitis and pneumobilia
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

is well recognised in adults in the context of gallstone ileus and after endoscopy.
One case of partially distended GB having air fluid level and pneumobilia
(Fig: E red arrow) was seen along with gall stone ileus, where the calculus was in the ileum in CECT abdomen (Fig: E white arrow).
6-8) This is also the preferred biliary anastomosis in pediatric patients, in which case resultant pneumobilia
is often present.
