Basilar artery fenestration: an unusual possible cause of ischaemic stroke?

BMJ Case Rep. 2018 Feb 12;2018:bcr2017222910. doi: 10.1136/bcr-2017-222910.

Abstract

Basilar artery fenestration is an uncommon congenital dysplasia and may be associated with ischaemic stroke. We present a case of a previously healthy 36-year-old man who presented with vertigo and vomiting. MRI showed posterior circulation territory infarction. High-resolution magnetic resonance angiography revealed a slit-like fenestration in the basilar artery. This patient had no traditional vascular risk factors or aetiology of cryptogenic stroke. The patient recovered from his neurological deficit after antiplatelet therapy and was given prophylactic aspirin therapy. There was no recurrence of symptoms after 12 months of follow-up.

Keywords: neuroimaging; neurology; stroke.
