Twenty-four cases of primary osteosarcoma in individuals over the age of 50 are described. This represents 6% of all osteosarcomas and 80% of osteosarcomas occurring over the age of 50 at this institution. Radiographically, features were similar to osteosarcoma in younger individuals. Females were more frequently affected than males (2.4:1). The radiographic features are discussed in detail, and the differential diagnosis outlined.
