Diagnostic Approach for Stroke Etiology in Takayasu Arteritis

Takayasu arteritis (TA) is a rare inflammatory arteritis that is usually affecting young women and causes ischemic changes in the vessel wall. In this report of TA leading to an acute ischemic stroke, we describe a treatment-resistant case, with short interval flares and the challenge of defining the stroke etiology as a large vessel occlusive disease vs. an arteritis flare. We have used CT and MRI modalities to show the active disease and got diagnostic answers from this tool.
