Abstract Objective: To explore CT imaging features of severe dysplasia of pancreatic intraductal papillary mucinous neoplasms(IPMN). Materials and Methods: As a retrospective study, the clinical, pathological and CT imaging data of 39 IPMN patients were collected and analyzed. CT imaging features of severe dysplasia were compared with slight to moderate dysplasia and invasive carcinoma. Results: CT features of severe dysplasia IPMN was partly similar with invasive carcinoma, suggesting it has a certain malignant tendency(cystic wall thickening, wall nodule, cystic wall and nodular enhancement). Meanwhile, it was partly similar to slight to moderate dysplasia IPMN, suggesting it has a certain benign tendency(less frequent occurence of peripancreatic haziness and enlarged lymph nodes). Conclusion: Severe dysplasia IPMN have certain CT imaging characteristics between those of slight to moderate dysplasia and invasive carcinoma. Therefore, more attention needed for severe dysplasia IPMN in clinics.
