ABSTRACT
Objective To investigate the imaging findings of primary bone malignant fibrous histiocytoma (PBMFH) in long bone. Methods MRI and XV ray examinations were performed in 10 patients with PBMFH in long bone confirmed by histology. CT scans were performed in 6 cases. Results Nine cases had single and 1 case had multiple lesions of single bone. Seven cases showed osteolytic bone destruction, and 3 cases showed mixed bone destruction. Only 1 case showed periosteal reaction. Gross bony ridge was seen in 3 cases on CT scan. All the patients demonstrated isointensity or hypointensity on T1WI, and slight hyperintensity signal on T2WI. Necrosis was seen in the lesion of 10 cases. Four cases showed obvious but heterogeneous enhancement after contrast medium injection. Eight cases had soft tissue mass beyond the scope of bone destruction. Conclusions Some imaging features may suggest the diagnosis of PBMFH in long bone.
