IntraCranial Meningioma.


Meningioma comprises if 25% of total CNS tumors detected. Meningiomas are extraaxial central nervous system tumors most often discovered in middle to late adult life, and are more often seen in women. Ninety percent of meningiomas are benign, 6% are atypical, and 2% are malignant. Most patients in whom a meningioma is diagnosed undergo resection to relieve neurological symptoms. Complete resection is often curative.

The objective of this study is to give idea about the descriptive epidemiology, clinical presentation and histopathology of current scenario at National Neurosurgical Referral Center, Nepal. 

This study is prospective study from the period of January 2015 to Sept 2019 in the department of neurosurgery, National Academy of Medical Sciences, NAMS, Bir Hospital. Inclusion criteria consists of all the histopathological proven cases of meningioma in department of Neurosurgery, NAMS, Bir Hospital during the same period. Rest of the CNS tumors were excluded from the study. 

Total no of meningioma operated were 150.The average age of presentation was 42 years. M: F ratio of 1:3. Most common affected age group was 30-50 years. The most common clinical symptoms for intracranial meningioma were headache followed by vomiting and paresis. Among intracranial meningioma, the most common location was convexity meningioma followed by sphenoid wing meningiomas and parasagittal meningiomas. Most common histopathological variety encountered was transitional meningioma. WHO grade I consists of majority of the tumors.
