Association between basilar artery fenestration and ischemic stroke: A case report

Intracranial artery fenestrations are congenital malformations that diagnosed rarely. Occasionally they are diagnosed incidentally. It is thought that they could be associated with different vascular pathologies such as aneurysms and arteriovenous malformations. The association between aneurysm and fenestration is well described in the literature. However, there are few case reports that mention the presence of an ischemic stroke due to basilar artery fenestration. Here, we purposed to discuss a patient who presented with vertigo and diagnosed with stroke caused by anterior inferior cerebellar artery infarction The patient benefited after thrombolytic therapy. We did not detect any traditional vascular risk factors or any other reason which might cause stroke. Magnetic resonance angiography revealed a fenestration in the proximal portion of the basilar artery. The patient's symptoms were stable at his follow-up and was discharged with prophylactic anti platelet therapy.
