Abstract:
Objective To improve the clinical and imaging diagnosis of benign fibrous histiocytoma of bone.Methods Imaging findingsin 14 patients with pathologically confirmed benign fibrous histiocytoma of bone were analyzed.X-ray plain film was performed in allpatients,CT scan and MR scan were done in 9 cases and in 5 cases respectively.Results The clinical symptom was mainly pain in the local lesion,soft tissue mass could be felt around the lesion in 2 cases.The single-lesion was 12 cases and multi-lesion was 2 cases.There were 22 lesions in 14 cases.Most lesions localized in long bones,totally were 17 lesions.9 lesions localized in cancellous bone,8 lesions localizedin diaphysis compact substance.X-ray plain film showed centric or eccentric osteolytic destruction,unilocular or multiocular with clearborder or sclerotic border,expansion,pathologic fracture and speckled calcification in some destruction lesions.Soft tissue mass could be seen around the lesion in few cases.CT was better than X-ray plain film in displaying calcification,cyst change,pathologic fracture and soft tissue masses in the destruction portion.MR presented as homogeneous signal on T_1WI and hyper-signal on T_2WI,sometimes was inhomogeneous,speckle-like low-signal and non-signal could be seen in the lesion on T_1WI and T_2WI.Few lesion shows intermixed signal on T_1WI and T_2WI.Conclusion Based on the typical imaging and clinical features,the correct diagnosis of benign fibrous histiocytoma can be made in most cases.
