Comparison of CT and MRI findings of different types of pancreatic Serous cystic neoplasm: combined with histopathology

Abstract Objectives A comparative analysis of the imaging findings across different types Serous Cystic Neoplasm（SCN）was conducted, the objective is to delineate distinct image characteristics, thus enhancing diagnostic accuracy. Methods The retrospective analysis involved 65 patients diagnosed with Serous Cystic Neoplasm (SCN) confirmed by pathology. Patients were categorised into macrocystic, microcystic, mixed, and solid types based on morphology. A comparative analysis of the imaging findings across different SCN types was conducted, elucidating their respective imaging characteristics. Additionally, microscopic pathological observations were juxtaposed to discern disparities among the various SCN types. Results Age, lesion location, clinical symptoms, and underlying diseases did not exhibit significant differences among the various types of Serous Cystic Neoplasm (SCN) (P > 0.05). However, the volume of lesions in the mixed type was notably larger than that in the microcystic type (P Conclusion Differences in CT and MR findings among different types of SCN suggest a correlation with their pathological basis.
