Walsh & Hoyt: Chondrosarcoma

This rare tumor arises from cartilaginous rests in or near bone. Although the age range is broad, it usually occurs in adults between 25 and 50 years of age. Males are primarily affected, with a male-to-female ratio of about three to one. Although chondrosarcomas most commonly occur in the extremities, they may occasionally arise intracranially, usually at the base of the skull, but also in other locations. In fact, chondrosarcomas represent only 0.15% of all intracranial tumors and 6% of lesions at the base of the skull
