Case in brief
A patient with a resected pancreatic mass was found to have mucinous carcinoma, which presented as a honeycomb-like multinodular cystic mass. Imaging studies showed poor contrast enhancement and an irregular contour, aiding in the diagnosis. The case highlights the importance of imaging characteristics in differentiating mucinous carcinoma from other pancreatic tumors.
What made this case unusual
The honeycomb-like appearance of the mucinous carcinoma mimicked that of a serous cystadenoma, presenting a diagnostic challenge.
Diagnostic / clinical pearl
Clinicians should consider poor contrast enhancement and irregular contours on imaging as key features that may help differentiate mucinous carcinoma from serous cystadenoma.
Why it matters
This case underscores the need for improved imaging criteria to accurately distinguish between different types of pancreatic tumors, particularly in rare presentations.
