A case of meningioma originating from the lateral wall of the cavernous sinus

Abstract

Meningioma originating from the lateral wall of the cavernous sinus is rare with only two reported cases. A 67-year-old man presented with recent memory disturbance and partial seizure. Magnetic resonance imaging revealed a well-demarcated and homogeneously enhanced mass lesion originating from the lateral wall of the left cavernous sinus. Total tumor removal was performed through a combined epi- and intradural approach. Histological diagnosis was transitional meningioma. Postoperative course was uneventful. This combined approach was helpful for cranial nerve preservation, total tumor removal, and bleeding control from the feeder of the tumor.
