Takayasu arteritis presenting as embolic stroke.

A 52-year-old Caucasian woman presented to the emergency department with symptoms of acute ischaemic stroke (right-side weakness, confusion and aphasia) that resolved completely after administration of tissue plasminogen activator. During stroke work-up, she was found to have an enhancing infiltrate of the aorta at the level of the take-off of the great vessels, most consistent with early Takayasu arteritis. After being discharged home on steroids and dual antiplatelet therapy, she returned 2 days later with re-presentation of weakness and aphasia. Further work-up revealed two intraluminal clots in the left common carotid and left internal carotid arteries that had not been discovered during previous testing. This case illustrates the need to screen for sources of embolic stroke in patients with Takayasu arteritis, especially those with recurring symptoms. © BMJ Publishing Group Ltd (unless otherwise stated in the text of the article) 2017.
