Well-defined, lobulated pancreatic head mass was measured as 26 x 24 mm. The mass showed a hyperintense signal on T1WI and T2WI and suppressed on fat-saturated images. The lesion does not show contrast enhancement. No adjacent structural invasion was noted. Findings are most suggestive of pancreatic lipoma.
Pancreatic lipomas are rare benign pancreatic tumors. In most cases, they are found incidentally. Pancreatic lipomas follow the signal intensity of the adjacent subcutaneous and mesenteric fat on MRI.
