[Usefulness of bone scintigraphy on diagnosis of malignant fibrous histiocytoma of bone].
We examined the roentgenographical features of 5 patients who were diagnosed histopathologically as malignant fibrous histiocytoma (MFH) of bone, especially on the imaging of bone scintigraphy. Two patients had multiple lesions on the initial examination, and two of 3 patients who showed solitary lesion on the first examination could be detected more pathological sites by bone scintigraphy which was studied within two months of the first investigation. On bone scintigraphy, the mixture of hot and cold lesions which was coincident with the osteolytic change on plan X-P could be noticed, and with the progression of osteolysis it had a tendency to increase the area of cold lesions. These features are similar to metastatic bone tumor which is the most questionable disease on diagnosis, and we conclude that bone scintigraphy will be absolutely necessary when MFH of bone is highly suspected in the clinical course.
