Chondrosarcoma of the skull base is a malignant tumor of cartilage origin. Clinical manifestations are nonspecific, early can be asymptomatic. We report a case of asymptomatic chondrosarcoma of the skull base which is difficult to confirm the diagnosis. The patient underwent Type A resection of chondrosarcoma of the skull base through the left subtemporal fossa approach, with postoperative radiotherapy. And the patient achieved good postoperative recovery. Therefore, chondrosarcoma of the skull base is a rare malignant tumor with slow growth. Early detection, excision, and postoperative radiotherapy can achieve a good therapeutic effect.
