Fifty-three cases of intracranial meningiomas were retrospectively analyzed with regard to the age and sex distribution, anatomic location, mode of presentation, surgical management, and outcome. Patient age ranged from 25 to 80 years (average, 47.7 years); overall male to female ratio was 1:1.9. Tumor locations were: 26.4% sphenoidal ridge, 20.8% convexity, 17% sagittal or parasagittal, 13.2% olfactory groove, 11.3% suprasellar, 9.4% infratentorial, and 1.9% multiple. Delayed diagnosis and referral were common and accounted for a higher number of patients with severe neurologic deficit and blindness. Forty-two patients underwent 47 surgical procedures for tumor removal; 38 were first operations and 9 were for recurrences. Tumor removal was total in 61% of the first and 33% of the repeat operations; the highest rates were achieved for lesions in the convexity (100%) and the lowest for basal (29%) meningiomas. Outcome following first surgery was excellent in 37%, good to satisfactory in 39%, and poor in 8% of the cases. There was a total of 6 (16%) postoperative deaths; however, the 30-day postoperative mortality was 5.3%. The recurrence rate was 5.6% after total and 30% after partial resection. Our results emphasize the importance of early diagnosis and treatment of intracranial meningiomas.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
