ABSTRACT
Objective To investigate the usefulness of 99Tcm-MDP whole body bone scan in bone malignant fibrous histiocytoma (BMFH).Methods Fifteen patients (11 males,4 females,age ranged from 23 to 60 years,average age (50.4±12.8) years) who had documented BMFH and underwent 99Tcm-MDP whole body bone scan were retrospectively analyzed.The appearance of increased uptake,decreased uptake or defect in radioactivity on bone was considered as positive.The typical scintigraphic manifestations of BMFH were summarized and compared to other radiological imaging data.Results All 15 patients showed positive results.The lesions involved femoral in 10 cases(66.7%),46.7%(7/15) of which was distal femur.The lesions also involved sacrum,tibia,humerus,radius each in 1 case and multiple lesions in 1 case.Among 27 lesions found,63.0% (17/27) showed strong increased radioactivity together with reduced or defect area and 37.0% (10/27) showed strong increased radioactivity only.X-ray found 20 lesions.Twelve cases underwent CT and 7 cases underwent MRI.Abnormal spots showed on CT and MRI were also positive on the whole body bone scan.Conclusions The most common site of BMFH is femur,especially distal femur.BMFH lesions are presented as strong increased radioactivity together with sparse and defect area on bone scan.The whole body bone scan may be an auxiliary examination to evaluate whether there are multiple bone lesions and bone metastasis.
