Falcine Mesenchmal Chondrosarcoma

We experienced a case of falcine mesenchymal chondrosarcoma in a 22-year-old pregnant woman. Cartilage cell tumors within the cranium are very rare, only less than 0.2% of all intracranial tumors. Because a few examples of mesenchymal chondrosarcoma in this locttion have been reported, we reviewed previous reports cases, to determine the natural history of intracranial chondrosarcomas. The distinguishing features of this rare tumor are compared with previous cases of itracranial tumors derived from cartilage.
