 Hello everyone. Welcome to MRCP Part 2. In this video, we will be discussing common pathologies of the pancreatic duct. These are thick slab MRCP images in a patient with colelithiasis showing loop shaped configuration of the main pancreatic duct. This is an anatomical variant and an incidental finding. This is a thick slab MRCP image of a patient with carcinoma gallbladder. The main pancreatic duct is seen to form a confluence with the terminal CBD and drain into the major adrenal papilla. An accessory duct is seen arising from the main pancreatic duct, forming a small loop, crossing the CBD and draining into the minor papilla. These findings are consistent with ANSA pancreatica which is a predisposing factor for pancreatitis. Here is another example of ANSA pancreatica. An accessory pancreatic duct is seen arising from the main pancreatic duct. It is seen to descend down, then ascend upwards, forming a loop, crossing the CBD and finally terminating into the minor papilla. Findings consistent with ANSA pancreatica. These are thick slab MRCP images of a patient with acute ontronic pancreatitis. The main pancreatic duct can be seen to cross the CBD and drain separately into the minor papilla. The common bile duct joins the ventral pancreatic duct and drains into the major papilla of dodenum. Same findings seen on this image. The MPD is seen to cross the CBD and drain into the minor papilla. Here is the ventral duct which joins the common bile duct and drains into the major papilla of dodenum. These findings are consistent with pantherias divism. These multiple hyperindense areas are likely necrotic areas in pancreatic parenchyma. Thick slab MRCP images in this patient show a dilated main pancreatic duct. CBD is prominent with abrupt cutoff of terminal CBD. Confluence of CBD and main pancreatic duct is not visualized. This is the so-called double duct sign. This patient had a lesion involving the unsanitary process of pantherias. Coronal thick slab MRCP and T2 non-fat site images show variant pancreatic duct lanatomy with dilated duct of virsung. Dilated duct of virsung is seen to join CBD and drain ventral pantherias at the major papilla. Main pancreatic duct is dilated with dilation of the side branches. Vacation is seen between dilated main pancreatic duct and dilated duct of virsung. A small out pouching is seen along the lateral aspects of main pancreatic duct with a thin channel which possibly represents duct of sanitary draining into the minor papilla. To recapitulate, variant pancreatic duct lanatomy is seen with dilation of duct of virsung joining the CBD and draining ventral pantherias at the major papilla. Main pancreatic duct is dilated with dilation of side branches. It is possibly draining into minor papilla via a thin channel representing the duct of sanitary draining. Communication is seen between the dilated main pancreatic duct and duct of virsung. Overall, these findings are suggestive of incomplete pantherias division and is the likely cause of recurrent pancreatitis in this patient. This MRCP image in a patient with chronic liver disease shows the main pancreatic duct forming a wide loop joining the terminal CBD to form the confluence. First and third part of dodenham can be appreciated with fluid contents within. Second part of dodenham is however not well visualized. Coronal T2-bedded images of the same patient shows the pancreatic parenchyma completely encasing the second part of dodenham. However no obvious proximal dilatation or obstruction is seen. These findings are consistent with complete annular pantherias. Thank you for watching the video.
