A 41 year-old woman presented with progressive gait imbalance, headaches, short-term memory loss, and involuntary laughter. Imaging revealed a large right petroclival meningioma causing obstructive hydrocephalus. We performed a posterior petrosal approach with intraoperative CSF drainage via ventricular drain for near-total resection of the tumor. A pedicled superficial temporalis fascia flap aided reconstruction. The patient had improved function following resection, aside from new right trochlear palsy
