Seizures in rare atypical and malignant meningiomas were significantly under-studied. Our aim was to examine the rates, predictors, and seizure control in these meningiomas, and to analyze associations between clinical characteristics and seizure free survival (SFS) following surgical resection in an Asian population. ⋯ Convexity and parasagittal area tumors as well as peritumor edema induce seizures. Preoperative seizures and tumor relapse predict seizures postoperatively. AEDs treatment improves SFS, and prophylactic AEDs eliminate early seizures after surgery. GTR has negative impact to seizure control.
