Case Review: X-ray & CT of Gallstone Ileus - a podcast by Daniel J. Kowal, MD

In this radiology lecture, we discuss the appearance of gallstone ileus on x-ray and CT.

Key points include:



* Gallstone ileus is a rare complication of chronic cholecystitis.

* Actually not an ileus, but a small bowel obstruction.

* Gallstone migrates through a fistula between gallbladder and small bowel (usually duodenum) and becomes impacted in the terminal ileum.

* Stone can also impact in the proximal ileum, jejunum, even in the duodenum/distal stomach causing gastric outlet obstruction (Bouveret syndrome).

* Rigler triad on abdominal x-ray: Small bowel obstruction, pneumobilia and gallstone in the right iliac fossa.

* Usually affects the elderly and treated surgically.
