14y MC Domestic Longhair with weight loss and lethargy. There is a soft‐tissue attenuating mass in the region of the right pancreatic
lobe. The duodenum is not clearly visible on the unenhanced images. On contrast‐enhanced images, there is peripheral contrast enhance-
ment of a large pancreatic mass with a central fluid‐attenuating region (b: arrows). The mass compresses the lumen of the duodenum
(b: arrowhead); however, it appears separate. The mass is contiguous with the left pancreatic lobe (c: arrows). Surgical biopsy revealed a
diagnosis of exocrine pancreatic adenocarcinoma.
