Ophthalmic artery aneurysms account for 5% of all cerebral aneurysms and are an important cause of morbidity and mortality related to subarachnoid hemorrhage. The diagnosis is often made only when the aneurysm is large enough to become symptomatic. They remain technically challenging for both neurosurgeon and interventional radiologist. We present the case of a 62-year-old woman admitted for transient loss of consciousness, followed by generalized tonic-clonic seizures. Computed tomography (CT) showed a subarachnoid hemorrhage (SAH), clinically graded as Hunt and Hess III. Magnetic resonance imaging (angioMR) and the four-vessel digital subtraction angiography (DSA) identified a ruptured, 8 mm left ophthalmic artery aneurysm. Embolization was the first therapeutic choice. Nevertheless, the attempt had to be aborted due to a combination of a hypoplastic right internal carotid artery (ICA) and an irregular atheromatous plaque on the left ICA, rendering the procedure unduly hazardous. Therefore, microsurgical clipping of the aneurysm became the procedure of choice. Postoperatively, the patient was in good condition, with no visual and neurological deficits. At 6 months follow up, she was assigned maximum scores of 5 and 8 on the Glasgow Outcome Scale (GOS) and Extended GOS (GOS-E), respectively. Aneurysm rupture represents a neurosurgical emergency and an early intervention (less than 48 h) is recommended to maximize the chances of deficit-free survival. The peculiarities of this case consisted in the combination between the size and the location of the aneurysm, abrupt presentation, and the impossibility of embolization due to bilateral ICA abnormalities, congenital (hypoplastic right ICA) and acquired (extensively atherosclerotic left ICA).
