Recurrent hemorrhage is a serious neurosurgical problem in adult moyamoya disease (MMD) patients. ⋯ During the follow-up period, recurrent hemorrhagic events continued to increase and deteriorated the patients' neurological conditions. The presence of intraventricular hemorrhage was a significant risk factor of recurrent hemorrhage.

Risk factors for pre- and postoperative seizures in supratentorial meningiomas are understudied compared to other brain tumors. ⋯ Nonskull base supratentorial meningiomas with surrounding edema have the highest risk for preoperative seizure. Long-term follow-up showing persistent seizures in meningioma patients with preoperative seizures raises the possibility that these patients may benefit from electrocorticographic mapping of adjacent cortex and resection of noneloquent, epileptically active cortex.
