Solitary Fibrous Tumor in the Buccal Space: MR Findings with Pathologic Correlation
a From the Departments of Diagnostic Radiology (J.H.S., S.O.Y., Y.K.J., J.H.L., J.C.H.), Dentistry (I.Y.S.), and Pathology (J.H.S.), Ulsan University Hospital, University of Ulsan College of Medicine, South Korea.
Summary: We report MR findings in a case of a solitary fibrous tumor involving the buccal space in a middle-aged man. On MR images, most of the mass was isointense and hyperintense to the muscle on T1- and T2-weighted images, respectively, and showed homogeneously strong enhancement on contrast-enhanced T1-weighted images. The medial peripheral portion, which was isointense on T2-weighted images and showed less enhancement on contrast-enhanced T1-weighted images, corresponded to the hypocellular and collagenous sclerotic area on pathologic correlation.
