A biliary calculus measuring 2.8×3.3×4.2 cm is seen in the jejunum with distention of the stomach and bowel proximal to it.
The gallbladder wall is thickened with multiple small gallstones within.
The patient was given oral contrast during the exam (noted in the second T1WI) where the stomach and proximal bowel appeared distended with high T1 signal fluid; this high T1 signal fluid was also observed in the gallbladder which indicated a bilioduodenal fistula.
