case_images: A 79-year-old man presented with epigastric pain. Unenhanced computed tomography scan of the abdomen demonstrated a 27-mm periampullary duodenal diverticulum filled with air (arrow in a) strictly adjacent to the distal portion of the common bile duct (arrowhead in a) which is 11 mm in maximum diameter (b). Symptoms regressed after NG decompression.

case_images: Contrast-enhanced computed tomography in a 70-year-old woman with nausea, vomiting, and slight jaundice. Intrahepatic bile duct dilatation is shown in a (white circle) with a small periampullary duodenal diverticulum with airfluid level demonstrated in b (arrowhead). Coronal reconstruction (c) highlights common bile duct dilatation and its close relation with periampullary duodenal diverticulum (arrow).
