Osteosarcoma frequently involves long bones; however, 8% of osteosarcomas involve the skull or mandible. Osteosarcoma is generally categorized based on location within the bone (central, surface, or extraskeletal) and histological grade (high-grade or low-grade). Osteoblastic osteosarcoma is a central, high-grade subtype and may be difficult to diagnose; it may present similarly to osteoblastoma, another rare, but benign, type of osteoblastic bone tumor.

Magnetic resonance imaging of the brain and skull base revealed the mass to be 2.8 cm in maximal diameter.
