The following results were obtained: 1) Meningioma was the most common in the 5th decade(46 cases, 37.7%) and the male to female ratio was 1: 2.1. 2) The pathologic types were meningothelial type(94 cases, 77.0%), transitional type, fibroblastic type and angioblastic type in order of frequency. 3) Convexity represented the single most common site of tumor(36 cases, 29.5%), followed by the parasagittal-falx, sphenoid wing, and cerebellopontine angle(CPA) in order of frequency. 4) The most common initial presentation was IICP signs and the mean duration of symptom was 22.5 months. 5) The most common CT finding was high density in PCT and strong homogeneous enhancement in ECT. Hypervascularity was seen in 83 cases(70.3%) on the angiography. 6) The total removal was done in 73.8% of patients and the postoperative mortality rate was 4.1%. 7) At the time of the analysis, 15 cases(12.3%) had shown evidence of recurrence, and the mean duration of recurrence was 31.8 months. 8) The follow up result was excellent in 75 cases(61.5%), good in 28 cases(23.0%), fair in 8 cases(6.6%), and poor in 6 cases(4.9%) and dead in 5 cases(4.1%).
