Endoscopic Ultrasound (EUS) as a diagnostic option for Annular Pancreas: A Case Report

Abstract

Annular pancreas is a rare congenital condition of the pancreas where the pancreatic tissue either partially or completely covers the duodenum by forming a ring. Endoscopic Ultrasound is rarely considered as the first diagnosis tool for annular pancreas. We here present a 48 years old man who was primarily provisionally diagnosed with pancreatic mass and was planned for pancreatoduodenectomy. But upon using endoscopic ultrasound a confirmative diagnosis of annular pancreas was reached.
