Ischemic stroke associated with intracranial aneurysm is rare but potentially happens because of emboli originating from sac or aneurysmal thrombosis extension to the parent artery. We describe two patients who present subarachnoid hemorrhage (SAH) soon after ischemic stroke. Case 1. A 51-year-old woman a history multiple endovascular therapy for ruptured basilar top presented double vision. Magnetic resonance imaging (MRI) revealed infarcts in right thalamus and left occipital cortex. Four days stroke, she suffered sudden onset headache, computed tomography (CT) showed diffuse SAH intraventricular hemorrhage. 2. 62-year-old man facial palsy sensory disorder. MRI an infarct pons. he became comatose CT SAH. Both cases develop adjacent aneurysms subsequently cause devasting rupture, suggesting as warning sign rupture. In such cases, early treatment should be considered.
