Figure 8b. Pancreatic duct stenosis following acute pancreatitis. (a) Presecretin MR image shows discontinuity of the main duct at the level of the pancreatic neck (white arrowhead), an adjacent high-signal-intensity fluid collection (black arrowhead), and diffuse ascites (arrow). (b) MR image obtained 7 minutes after secretin injection shows stenosis of the main pancreatic duct in the pancreatic neck (white arrowhead) and diffuse ascites (arrow). The fluid collection adjacent to the pancreatic neck (black arrowhead) appears brighter than on the presecretin image, a feature suggestive of a connection to the duct. (c) ERCP image helps confirm the presence of stenosis (white arrowhead) and absence of disconnection of the duct. The fluid collection (black arrowhead) is filled with injected contrast material, which indicates disruption of the duct. The patient underwent percutaneous placement of a pancreatic stent (not shown) and did not need open surgery.
