Embryological Development and Congenital Anomalies of the Pancreas: A Pictorial review

Aliki Lazaridou, Sofia Gioulvanidou, Charalabos Mascalidis, Ioannis Tsitouridis


This review highlights the characteristics in Imaging of congenital anomalies and variants of normal anatomy of the pancreas by providing an overview of the most common among them. Important embryologic events are noted to emphasize the mechanisms of their formation. The radiologic appearance at different modalities is presented, focusing mainly on computed tomography, magnetic resonance imaging, endoscopic retrograde cholangiopancreatography, and MR cholangiopancreatography. The purpose of this essay is to familiarize clinicians and radiologists with these appearances and help prevent misdiagnosis in everyday practice.
