Bone Tumor Diagnosis and Treatments

Primary and secondary bone tumours usually result in areas of increased tracer uptake on bone scans because of osteoblastic reaction of the bone surrounding the tumour (Kirchner, 1980). Rarely, tumours may result in areas of reduced tracer uptake (Georgen et al, 1974; Sy et al, 1975; Goris et al, 1980; Kado et al, 1980; Bushnell et al, 1983; Makhija, 1983; Weingrad et al, 1984). In this report, a case of osteosarcoma with prominent fibroblastic reaction is presented as it resulted in the unusual finding of a “cold” lesion on bone scintigraphy.
