Intracranial meningiomas: Experience at a tertiary health-care center in India

Introduction: Intracranial meningioma is one of the most common primary intracranial tumors. It constitutes 10%–15% of all brain neoplasm across the globe, whereas in India, their occurrence varies from 11.6% to 21%. These tumors are neuroectodermal in origin and are believed to arise from arachnoid cap cells. These tumors are mostly histologically benign with Patients and Methods: The survey intended to study the incidence of meningioma among other intracranial tumors, the clinical profile of the patients, surgical outcomes, and long-term results. The study included all the cases of intracranial meningioma admitted in the Department of Neurosurgery, Rajendra Institute of Medical Sciences, Ranchi, between the time period of January 2012–December 2015. All patients, irrespective of age and sex, who were diagnosed of intracranial meningioma based on clinical data, radiological evidence, and histopathology, were included in the study. A total of 106 patients were included in the study. Results: The study revealed that the incidence of intracranial meningioma among other brain tumors is 14.45% and the disease shows a female preponderance. Meningiothelial meningioma is the most common histological variant reported during the study. Seizure and cranial nerve damage were the common complications observed among the patients during the follow-up study. Total excision of the tumor is the treatment of choice. Seventy-seven percent of the patients show good recovery with Glasgow Outcome Score of 5. Conclusion: Intracranial meningiomas are common intracranial tumors. They affect people in fifth decade of their life and show a female preponderance. They commonly present with symptoms such as seizure and headache. Meningothelial meningioma is the most common histological subtype. Total excision of the tumor mass has been found effective in preventing reoccurrence. Microsurgical techniques give good results with minimum mortality.
