We describe our experience with a 74-year-old male with weakness, ataxia & CN 7/8 deficits; MRI demonstrated a large right side petrous-tentorial meningioma. The right Retrosigmoid Suprameatal Transtentorial approach was performed with near-total resection. Postoperatively ataxia improved but he developed internuclear ophthalmoplegia (learning point in the video about handling peri mesencephalic venous bleeding) which resolved in subsequent follow-up at 1 year. In addition, we discuss technical nuances of maximizing retro sigmoid corridors.
