Basilar artery fenestrations (BAF) are rare vascular anomalies. Surgical intervention for aneurysms in this vascular segment is exceptionally arduous because of the complexity of the neurovascular structures in the vicinity of the brainstem. Endovascular therapy (ET) is the treatment of choice because of its safety and efficacy. Here, we report a 62-year-old female presenting with a two-day history of sudden onset severe headache, vomiting, and altered sensorium. A computed tomography (CT) and subsequent CT angiogram (CTA) revealed subarachnoid hemorrhage (SAH) and BAF with an aneurysm on each arm of the fenestration. Digital subtraction angiogram (DSA) with a three-dimensional rotational angiogram (3DRA) was employed before initiating ET. We used coiling and flow diversion to exclude the aneurysms from circulation. A six-month follow-up angiography reconfirmed the complete obliteration of the aneurysms. There was no focal neurological deficit.
