Mucin-producing tumour that arises from the epithelium of the main pancreatic duct or a branch. It can be a cause of recurrent pancreatitis and Diffuse or segmental dilation of pancreatic duct, atrophy of pancreas, cystic ectasia of branch ducts “”bunch of grapes””, intraductal papillary solid mass, multicystic mass are present. Cystic pancreatic lesions may be benign.
MRCP
• Cystic lesions communicating directly with the main pancreatic duct suggests branch duct IPMN.
• Markedly dilated main duct with or without luminal soft tissue lesion (low signal on T2) with main duct IPMN.
• The mucinous secretions are high signal on T2 (aggregations of mucin can mimic the tumour itself and are low signal on T2).
