A solitary fibrous tumor (SFT) originating in the pancreas is rare. We report a 55-year-old woman with an asymptomatic pancreatic mass incidentally discovered on abdominal ultrasonography. Contrast-enhanced computed tomography (CT) showed a well-demarcated exophytic mass in the pancreatic head with prolonged and delayed enhancement. The mass showed hypointensity on T1-weighted images and heterogeneous hypointensity with spotty hyperintensity foci on T2-weighted images. Fluorodeoxyglucose-positron emission tomography (FDG-PET)/CT showed no significant FDG uptake. The resected mass was composed of spindle cells that were positive for CD34; and hemangiopericytomatous vessels were focally detected. The mass was finally diagnosed as an SFT of the pancreas.
