Annular pancreas in elderly male: a case report

Annular pancreas (AP) is a rare congenital abnormality in which the ventral portion of the pancreas fails to rotate with the duodenum during embryological development, thus causing the ventral portion to remain partially or fully enveloped around the duodenum. The actual incidence of AP is unknown, as many cases are asymptomatic and undiagnosed. Adults with AP may present with a variety of symptoms suggestive of gastric outlet obstruction, or may present with gastrointestinal bleeding, pancreatitis, or biliary obstruction. Surgery continues to remain the diagnostic “gold standard” for AP, but imaging techniques such as CT, MRCP (Magnetic resonance cholangiopancreatography), ERCP (Endoscopic retrograde cholangiopancreatography) and EUS (Endoscopic ultrasound) can now be used to make the diagnosis. We report the case of a 65-year-old gentleman who presents with symptoms of gastric outlet obstruction who was diagnosed with AP by CECT (Contrast enhanced computed tomography) and MRCP.
