Thirty cases of spinal AVM (male 23 and female 7) are described. The main clinic symptoms and signs were paralysis and dysfunction of sensation. The Queckcnstedt's test was an important examination.The protein content of CSF was 0.85-15.76 g/L(average 2.63 g/L), Twenty-three cases (76.6%) of spinal AVM were found in thoracic segment. The pathological types were arterio-venous malformation, capillary angioma and.spongy angioma. The best treatment of spinal AVM is microsurgical therapy, totally removing it. All of the patients were survival.They were followed up for 3 months-9 years. 14 cases (46.7%) returned to original work, 10(33.3%)could live independently, and only 6(20%) did not show any improvement.

Twenty four cases of meningioma of the sphenoid ridge were reported. The common symptoms and signs of this tumor were summarized. For practical use, it may be classified as medial and lateral types. The symptoms and signs of these two types are different. Carotid angiograms are helpful to show the blood flow of the tumor. This method cannot be replaced by CT scan. The tumors were removed in fifteen patients totally, among them two died. The authors considered that the most important things for successful operation are to control bleeding carefully, to treat all the blood vessels at the base of the tumor properly and to protect its surrounding important structures during the operation.
