    We present the first reported case that describes the complete resolution of a meningioma following endovascular embolization. A man in his 70s who presented with gait abnormalities and recurrent falls was diagnosed with normal pressure hydrocephalus (NPH) and found to have a small incidental meningioma. Due to ventriculoperitoneal (VP) shunt placement for cerebrospinal fluid diversion, the patient developed a bilateral subdural hematoma (SDH) requiring evacuation and drain placement. The patient also underwent bilateral middle meningeal artery (MMA) embolization. During the embolization, the known right frontal meningioma was embolized as it was supplied by the right MMA. The patient remained neurologically stable after this procedure. His follow-up magnetic resonance imaging (MRI) 1 year and 2 years after the procedure demonstrated complete resolution of the meningioma.
