Bouveret's syndrome: diagnosis by helical CT scan.
Calculous cholecystitis severe enough to result in pyloric outlet obstruction is a rare occurrence. Impaction of a large calculus in the duodenum or stomach as a consequence of fistula formation is usually diagnosed on upper gastrointestinal series. Computed tomography is uncommonly used to diagnose this condition and was diagnostic in our patient.
