Figure 39. Intraductal mucus-producing lesions mimicking chronic pancreatitis. (A) MRCP shows a mild dilatation of the pancreatic duct and side branches (arrowheads) and no filling defects. (B) Fat-suppressed TSE T1-weighted image through the pancreas shows a subtle decrease in signal intensity in the tail (arrow). (C, D) ERCP at the level of the head and body (C) and tail (D) of the pancreas shows that the duct was partially filled with mucus (arrows).
