Abstract:Objective: To explore imaging contrastive diagnosis of adult benign fibrous histiocytoma (BFH) of bone. Methods: Imaging findings in 11 patients with adult BFH of bone were analyzed contrastively and retrospectively. Results: Lesions mainly located in long bone of limbs, single lesions in 10 cases, 1 case with multiple lesions. X-ray plain film showed osteolytic destruction, unilocular or multiocular with clear border or sclerotic border, mild expansion. CT was better than X-ray plain film in displaying calcification, cyst change, pathologic fracture and soft tissue masses in the destruction portion, around the hardened edge and the thickness of a hardened edge also showed better. MRI clearly showed the funicular fiber on focal low signal within lesions, soft tissue mass and peripheral edema of reactivity could be seen clearly. Conclusion: Diagnostic value of all kinds of imaging examinations with BFH have their strong points, imaging manifestations in combination with clinic can further improve the level of imaging diagnosis of BFH.
