[99mTc-HMDP accumulation in soft tissue tumor].

ABSTRACT

Accumulation with bone scintigraphy using technetium-99m hydroxymethylene diphosphonate (99mTc-HMDP) in 68 cases with radiographically or pathologically verified soft tissue tumor was examined. Radiographical or histopathologic diagnoses of the 68 cases included; 14 lipomas, 11 liposarcomas, 11 neurinomas or neurofibromas, 6 malignant lymphomas, 5 malignant fibrous histiocytomas, 5 hemangioma, rhabdomyosarcomas, 2 Langerhans cell histiocytoses, 2 desmoid tumors and one each of neuroblastoma, hemangiopericytoma, angiomyxoma, plasmacytoma, liomyosarcoma, lymphangioma, fibrosarcoma, elastofibroma, synovial sarcoma, and ganglion. Thirty-seven (54%) showed positive accumulation and 31 were negative. One half of soft tissue tumors can be accumulated by 99mTc-HMDP.
