V022: POSTERIOR INTERHEMISPHERIC APPROACH FOR RESECTION OF FALCOTENTORIAL MENINGIOMA
Sean B Lyne, MD; Wenya L Bi, MD; Brigham and Women's Hospital
Falcotentorial meningiomas pose operative challenge given their deep location and intimate relationship to deep veins. We present a 60 year-old woman who presented with progressive confusion, imbalance, and right sided weakness. MRI demonstrated a large falcotentorial meningioma compressing the tectum and internal cerebral veins downwards. We performed a posterior interhemispheric approach for early devascularization, followed by gross gross total resection and excision of the involved falx and tentorial incisura, with preservation of critical neurovascular structures.
