Obstructive jaundice due to peripapillary diverticulum with enterolith compressing the choledochus

Abstract

Duodenal diverticula are relatively rare and cause subtle clinical signs and symptoms. Their diagnosis is often 
delayed until complications develop. We present herein a patient with duodenal diverticulum (enterolith within the 
diverticulum) mimicking a periampullary neoplasm, who presented with obstructive jaundice. Even if complications 
occur, an exact preoperative diagnosis may be very difficult especially in patients with previous cancer surgery at this 
site.
