Abstract:
Objective To explore the CT and MRI characteristics of pancreatic mucinous cystic neoplasm with associated invasive carcinoma(MCN-AIC)and their clinical application.Methods A retrospective analysis was conducted on the CT and MRI manifes-tations,clinical presentations,and laboratory results of 10 patients with pathologically confirmed MCN-AIC.Results Four of 10 patients presented to the clinic with abdominal pain.Plain CT showed all 10 lesions with hypointensity,and enhanced CT showed 8 lesions with mild delayed enhancement.MRI showed 8 lesions with limited diffusion on diffusion weighted imaging(DWI).2 lesions had cal-cification and 8 lesions had no calcification.6 lesions were located at the pancreatic head,3 at the pancreatic tail,and remaining one at the pancreatic neck.In addition,main pancreatic duct dilatation in 6 leisons,no main pancreatic duct dilatation in 4 lesions,thickened cyst wall in 10 lesions,wall nodules in 4 lesions,no wall nodules in 6 lesions,and intratumoral segregations in 5 lesions,5 lesions without segregations.Conclusion The CT and MRI manifestations of MCN-AIC have certain characteristics and play an important role in imaging diagnosis,which can provide a reference basis for the treatment.
