Pancreatic congenital anomalies and their features on CT and MR imaging: a pictorial review

To review the congenital anomalies of the pancreas with their main clinical manifestations and key imaging findings on CT and MRI.

Anomalies of pancreatic development are frequent and generally asymptomatic, but can mimic and predispose individuals to pancreatic or peripancreatic pathologies, such as pancreatitis or malignancy. Their correct diagnosis may help avoid unnecessary further investigations and procedures, or establish adequate treatment when they manifest clinically. Differentiating pancreatic congenital anomalies from their main radiological mimics constitutes a challenge for the radiologist and requires familiarity with key imaging findings.

The imaging findings of CT and MRI are essential for the correct diagnosis of congenital pancreatic anomalies.
