1. Main Point

This paper would like to present one of the possible causes of recurrent acute pancreatitis, namely the bifid pancreas. This anatomical variant is best investigated only with the abdominal MRI, including MRCP (MR cholangiopancreatography).

2. Clinical Image

Bifid tail of pancreas (fish tail pancreas) or pancreas bifidum is extremely rare congenital malformation. This anatomical variant is characterized by an abnormal branching of the main pancreatic duct. This anomaly is generally not associated with abdominal pain or pancreatic disease. Most cases are asymptomatic, detected incidentally. Nevertheless, pancreas bifidum may cause acute pancreatitis [1]. Herein, we report the case of a 65-year-old female patient with a previous recurrent episode of acute pancreatitis. Patient had none clinical predisposing factors for acute pancreatitis. Abdominal MRI, including MRCP (MR cholangiopancreatography), was performed to better evaluation of the biliary tract and pancreatic parenchyma. MRCP (Figure 1) showed duplication of the major duct in the tail of the pancreas. Axial T2-weighted image (Figure 2) showed ventral and dorsal pancreatic buds with the typical fish tail appearance.

In the absence of clinical predisposing factors (alcohol or smoking history), in cases of acute pancreatitis, it is advisable to perform an abdominal MRI, including MRCP to rule out anatomical abnormalities as predisposing factors. Our case corroborates what reported in very few literature cases [2] of association between acute pancreatitis and bifid pancreas, besides displaying the typical MRI findings.
