Cerebral aneurysms, characterized by localized arterial dilations, represent a significant neurological concern, often remaining asymptomatic until a critical event triggers clinical manifestation. We present the case of a 64-year-old male who presented with a severe headache and visual disturbances. The diagnostic workup revealed significant dilatation of the right posterior cerebral artery, confirmed as a large aneurysm through magnetic resonance angiography. Endovascular coiling was chosen as the primary management option, resulting in a successful procedure and near-complete resolution of symptoms. This case report underscores the clinical significance of posterior cerebral artery aneurysms, a relatively rare yet potentially life-threatening vascular anomaly.
