|
|
The authors analyzed the clinical and pathological characteristics of 66 meningioma patients, operated and pathologically confirmed at the Department of Neurosurgery & Pathology, Yeungnam University Hospital from 1984 to 1992.
@ES The results arte as follows :
@EN 1) Meningioma was the most common in the 6th decade (39.4%) and the overall ratio of male to female was 1:25.
2) The most common pathologic types were meningothelial type (30.3%) and transitional type (30.3%).
3) The predilection sites were convexity, parasagittal and falx in order o frequency.
4) The most common clinical feaiures were IICP signs (57.6%).
5) The marginal contour of the tumor on brain CT were more irregular, mushrooming and fringing pattern in the case of angioblastic and atypical type. The brain edema was more severe in the case of these types. However, these findings had no
correlation
with prognosis.
6) There were 9 atypical cases (13.6%).
7) The total removal was done in 53 cases (80.3%) and the postoperative mortality rate was 7.5%.
8) The recurrence rate was 9.0% and the mean duration of recurrence was 36.5 months. The recurrence depended on grade of the surgical removal rather than the pathological type.
