Abstract:
To provide a guideline of accurate diagnosis and proper methods of treatment of meningioma, the most common benign intracranial tumor, the authors studied 94 cases of intra & extracranial meningioma who had been diagnosed and operated at the Department of Neurosugery, Yonsei University College of Medicine from November, 1966 to October, 1982. The results were as followings. 1) The ratio of male to female was 1 to 1.4 and 30.8% of the 94 patients were in the 4th decade of age and another 30.8% in the 5th decade. 2) The predilection sites were parasagittal and falx(37.2%), sphenoid ridge(15.9%), convexity(14.9%), and suprasellar(10.6%) area. 3) The common initial clinical features were headache(55.5%), visual disturbance (16.0%) and seizure (14.9%). In radiologic diagnostic tests, there were abnormal findings in over a half on plain skull X-ray, and brain CT scan was regarded as the most accurate and safe method. Cerebral angiography provided the informations such as vascularity, venous drainage and relationship with the venous sinus. 4) Among the 6 cases of basal posterior fossa meningioma, the surgical excision of the tumor could be performed totally in 2 cases and subtotally in 4. 5) In 8 recurrent cases, all the tumors except one were located at parasagittal area and they were 3 hemangiopericytic, 2 hemangioblastic, 2 angiomatous and 1 meningotheliomatous type. 6) The Laser was thought to be very effective surgical tool to remove vascular tumor, such as meningioma, with its unique properties of non-mechanical bloodless evaporation of tumor and minimizing of brain edema.
