Patient 5 presented comatose with a ruptured left anterior insular and basal ganglia AVM. (A) Axial computed tomography angiography demonstrated a large hematoma in the basal ganglia with midline shift. She underwent emergency decompressive hemicraniectomy, after which digital subtraction angiography showed a modified Spetzler-Martin grade III+ AVM (left internal carotid artery injection, (B) lateral and (C) anterior oblique views). (D) Her AVM was significantly smaller 3 years after Gamma Knife radiosurgery. Her AVM was resected completely through an anterior transsylvian-transinsular approach, as confirmed by postoperative angiography (left ICA injection, (E) anterior oblique and (F) lateral views).
