Abstract:
Objective To explore the imaging radiological and clinicopathological characteristics of benign fibrous histiocytoma (BFH) of bone, in order to improve the imaging diagnostic accuracy of the disease Methods Radiological and clinical data of 16 patients with BFH confirmedbypathology were retrospectively analyzed , and relevant literatures were reviewed. Results The X-ray findings of 14 BFHpatients were osteolytic lesion , expansive destruction of bone,without soft tissue involvement, 10 with residual apophysis,9 with osteosclerosis marginal; CT was performed on 2 patients. Expansive destruction of bone and soft tissue densities were seen inside the loops , 1 case remarkable enhancement of the lesion. MRI was performed on 9 patients and 5 cases showed long T1 and T2 signal intensity; 1case showed equal T1 and long T2 signal intensity in cystic part and equal T1 and T2 signal intensity in the solid part. One patient had pathological fracture, and the surrounding soft tissue invaded, showing equal T1 and long T2 signal intensity. Two lesions located at spinous process of cervical vertebra , showing long T1 short T2 and equal T1 and T2 signal intensity. Linear low signal separation shadow in T1 and T2 could be seen in 6 cases. Long T1 and short T2 sclerotic ring were seen in 4 cases. Solid part of tumor and linear separator were obviously enhanced. Conclusions The radiological findings of benign fibrous histioeytoma of bone indicate some characteristics. The combination with X-ray , CT and MRI examination is helpful to improve the diagnostic accuracy of the disease before operation.
