Imaging Diagnosis of Tumors and Tumor-like Lesion of Fibrous Histiocyte Oringin in the Femora:An Analysis of 17 Cases / 实用放射学杂志

ABSTRACT

Objective To study the imaging diagnosis of tumors and tumor-like lesion of fibrous histiocyte origin in the femora.Methods Imaging features of femoral fibrous histiocyte neoplasm and tumor-like lesion were restrospectively analyzed in 17 cases ,including 16 cases proved by surgery and pathology, and one case was follow-up studied in five years.All cases were examined by plain X-ray flim, CT scan in 5 cases. Results There were fibrous dysplasia of bone in 8 cases,non-ossifying fibroma in 5cases ,fibrosarcoma of bone and benign fibrous histiocyte tumor of bone in 1 case respectively ,malignant fibrous histiocyte tumor of bone in 2 cases. They were diagnosed correctly before operation in 13 cases (13/17,76.5%) and misdiagnosed in 4 cases.Conclusion The most of femoral fibrogenic tumor and tumor-like lesion can be dingnosed correctly before operation ,because of they are of specific imaging features, while femoral fibrous histocyte original tumors are not of specific imaging findings, it must combine with clinical and pathologic data in diagnosis.
