ABSTRACT
Objective To evaluate the imaging features of benign fibrous histiocytoma (BFH).Methods Imaging data were retrospectively collected and reviewed in 11 patients with pathologically proved BFH.Of the 11 patients,X-ray was performed in all patients,MR scans in 6 patients,and CT scans in 4 patients.Results ALL lesions detected were a solitary lesion.The distribution of BFH was in the tibia (n =5 ),femur ( n =3),fibula ( n =1 ),sacrum ( n =1 ),and thoracic vertebrae ( n =1 ).X-ray features included eccentric osteolytic lesions in 7 patients and centric in 2 patients,with clear boundary and thinning of the cortex,and 7 patients with varying degrees of ossified border were found. CT scan shows bone destruction with density similar to soft tissue.The majority of lesions ( n =3 ) were observed in the expanding shell of bone,2 patients in the tibia and 1 patient in the thoracic lesions with cortical bone perforation.The thoracic lesion as soft tissue mass was detected. All of the lesions detected in CT showed no periosteal reaction.In patients with MR images,hypo to isointense signal intensity on T1WI and hyperintense signal intensity on T2WI was found. All lesions on post-contrast T1WI were detected with homogeneous or heterogeneous lesion with moderate or significant enhancement.Conclusion Imaging features were typical for MFH which is useful tool helping correct diagnosis of MFH.
