Significance of MRI in Bouveret's Syndrome

Impaction of a big gallstone in the duodenum, after migration through a bilioduodenal fistula, causing gastric outlet obstruction (GOO) is known as Bouveret's syndrome. In computed tomography (CT), pneumobilia and calcified bile stone in duodenal bulb leading to GOO is typical for diagnosis. Most of the cases presented to date are diagnosed with CT and their imaging features were discussed. On the other hand, there are very few published researches about the magnetic resonance imaging (MRI) findings of Bouveret's syndrome. In this paper, a case of Bouveret's syndrome diagnosed with MRI is discussed in the view of the present literature. KEY WORDS: Bouveret's syndrome, Cholecystoduodenal fistula, Gastric outlet obstruction, Gallstone ileus, MRI.
