Key result
Primary osteosarcoma in adults over 50 shares radiographic features with younger patients alongside female predominance.
Why the study?
Radiographic features of primary osteosarcoma in individuals over the age of 50 were not well characterized compared to younger patients.
Observational (n=24)
No
Primary osteosarcoma in patients over 50 presents with radiographic features similar to those seen in younger individuals.
May support similar diagnostic approach in older adults; leaves open confirmation of female predominance in larger cohorts.
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.

deSantos et al. (1978) conducted an observational in Primary osteosarcoma (n=24). Radiographic evaluation was evaluated on Radiographic features. Radiographic evaluation of primary osteosarcoma in 24 individuals over age 50 revealed features similar to younger patients, with a female predominance (2.4:1).
