A 45-year-old man presented with chief complaint ofepigastric pain of two months duration. It was notassociated with vomiting or abdominal distension. He hadno significant past illness. Clinical assessment, blood countresults, and liver and pancreatic enzyme levels werenormal.

Abdominal ultrasonography revealed calcified lesion inthe liver. Multidetector CT showed normal pancreatic tissueand pancreatic duct encircling the descending duodenum(Fig. 1).

Annular pancreas is a rare congenital anomaly (1/20,000people) in which a band of pancreatic tissue that arises fromthe head of the pancreas surrounds the descendingduodenum, either completely or incompletely [1]. Theexact etiology is still not known. Diagnosis is made onthe basis of CT and MR imaging findings that depictpancreatic tissue and an annular duct encircling thedescending part of duodenum.
