Abstract:
Intraductal papillary mucinous neoplasm (IPMN) of the pancreas is a cystic tumor of the pancreas with some malignant potential. According to the degree of pancreatic duct expansion and the location of the tumor, it can be divided into main-duct type, branch-duct type, and mixed type. According to the degree of atypia, it can be classified as low-grade dysplasia, high-grade dysplasia, or invasive IPMN. According to histological morphology and immunohistochemistry, there are four subtypes: gastric type, intestinal type, pancreaticobiliary type, and eosinophilic type. Ultrasound is commonly used in screening and follow-up, while CT, MRI/MRCP, and EUS can identify IPMN with high-risk and anxiety characteristics, which are valuable in determining the timing of surgery and patient status. Imaging omics is highly accurate in assessing the degree of dysplasia and can be used to identify people at high risk of malignant transformation. In this article, the clinical manifestations, pathology, and imaging features of IPMN are reviewed in the light of the relevant guidelines and literature in recent years, in order to deepen our understanding of IPMN and thus improve the accuracy of imaging diagnosis.
