Simultaneous occurrence of aneurysmal subarachnoid hemorrhage and remote intracerebral hemorrhage--case report.

A 77-year-old female presented with a rare aneurysmal subarachnoid hemorrhage accompanied by a remote hypertensive intracerebral hemorrhage. With a past history of hypertension, she suddenly developed right hemiparesis followed by delayed loss of consciousness. Left carotid angiography demonstrated a left internal carotid-posterior communicating artery aneurysm. The intracerebral hematoma was located in the posterior limb of the internal capsule ipsilateral to the ruptured aneurysm. The aneurysm was clipped with a fenestrated clip 3 weeks after the onset. The rise in blood pressure at the onset of intracerebral hemorrhage probably caused the rupture of the internal carotid-posterior communicating artery aneurysm.
