[Bone scintigraphy in two cases of primary vertebral osteosarcoma in adults].

The primary vertebral osteosarcoma in adults is a rare tumor which represents less than 2% of all osteosarcomas. We present the cases of two men (40 and 33 years old) who began with pain and neurological compression symptoms. The imaging methods used to study the tumors were X-rays, CT, MRI and bone scintigraphy with 99mTc-HMDP. After the pathological diagnosis, the tumors were removed surgically and the treatment was completed with chemotherapy and radiotherapy. In this report the authors review the published cases of vertebral osteosarcoma, its epidemiology, clinical presentation and characteristics in the different imaging techniques.
