title: Chondrosarcoma at the skull base.
abstract: A rare case of chondrosarcoma at the skull base is presented. Computerized tomography scan was very helpful in delineating the exact extent of the tumor. Chondrosarcoma is a slow growing malignant tumor which metastasizes very late. Usually it is radioresistant, but when surgery is not feasible, irradiation treatment is worth a trial.
