[Acute pancreatitis disclosing an uncommon form of annular pancreas].

We report a case of an acute pancreatitis revealing an annular pancreas associated with a pancreas divisum. Diagnosis was performed by endoscopic retrograde pancreatography with successful injection of major and minor papillae. Coexistence of pancreas divisum and annular pancreas is a rare congenital anomaly. Our case is original because the annular duct system encircling the duodenum is the ventral pancreas duct.
