title: Primary osteogenic sarcoma of the brain. Case report.
abstract: The authors report a case of primary osteogenic sarcoma of the brain. Negative autopsy findings, complete bone radiographs, and bone-scanning techniques were consistent with a primary tumor focus in the right temporopietal region of the brain. The authors suggest an origin from a primitive multipotential mesenchymal cell.
