title: [Cystic meningioma originating from cavernous sinus: a case report].
abstract: A 72-year-old man presented with gait disturbance and right homonymous hemianopsia. Magnetic resonance (MR) imaging showed a solid mass around the left cavernous sinus with rostral development of a multi-lobulated cystic component. The tumor was totally removed including the cystic wall via the left transsylvian approach with orbito-zygomatic craniotomy. Most of the tumor was attached to the lateral wall of the left cavernous sinus. Histological examination showed a meningioma WHO grade I with meningothelial meningioma formed lobules with intranuclear inclusions. His neurological symptoms disappeared immediately after the operation. Postoperative MR imaging revealed total removal of the tumor including the large cystic component.
