Intrameningioma metastasis: A case-based literature review

Meningiomas are the most common primary intracranial tumors, representing 36.4% of Central Nervous System (CNS) tumors and 14.3–19% of primary intracranial neoplasms [1]. Women have a predisposition during their 50 s and 60 s, and the incidence is 4:100,000 with a female to male ratio of 2.5:1 [2,3]. Most meningiomas are asymptomatic. For symptomatic meningiomas, surgery is the treatment of choice [4]. Ionizing radiation, surgical trauma, genetic factors like Neurofibromatosis Type 2, and hormonal factors have all been characterized as risk factors for meningioma [5].
