Neurological examination showed bilateral papilledema. Magnetic resonance imaging revealed a solid, enhancing tumor in the right trigonum with a hypointense cystic component located in the center of the tumor. The lesion was totally resected via a superior parietooccipital transcortical approach. Histological examination showed an anaplastic (malignant) meningioma with architectural disarray, high mitotic activity (20\/10 hpf), necrosis, and cytological atypism.
