What is it about?

Mucinous carcinoma of the pancreas has been rarely documented. Consequently, studies on imaging criteria for distinguishing mucinous carcinoma from other pancreatic tumors remain insufficient. Herein, we report a resected case of mucinous carcinoma of the pancreas, including correlation analysis between imaging and pathology.

Why is it important?

Mucinous carcinoma has been reported to have a more favorable prognosis than that of ordinary pancreatic ductal adenocarcinoma (PDAC). Therefore, an accurate imaging diagnosis of mucinous carcinoma is important for suitable treatment. Imaging studies of mucinous carcinoma reveal a honeycomb-like spherical or multinodular cystic mass with poor contrast enhancement.

Perspectives

Mucinous carcinoma of the pancreas can present as a multinodular cystic mass with a honeycomb-like structure. A key feature distinguishing it from serous cystadenoma is poor contrast enhancement, which might be accompanied by an irregular contour.
