# Ischemic Stroke as the First Manifestation of Takayasu Arteritis: A Case Report

## TL;DR

A young woman experienced an ischemic stroke, which was later found to be the first sign of Takayasu arteritis, highlighting the need to consider this condition in similar cases.

## Contribution

This case report highlights the rare presentation of Takayasu arteritis as an initial symptom of ischemic stroke in a young adult.

## Key findings

- Ischemic stroke in young adults can be the first manifestation of Takayasu arteritis.
- Endovascular reperfusion strategies may be effective in treating stroke caused by large-vessel inflammation.
- Early recognition of inflammatory vasculitis is crucial for appropriate treatment initiation.

## Abstract

Introduction: Ischemic stroke in young adults is uncommon and is frequently associated with rare etiologies, including autoimmune diseases and vasculitis. Takayasu arteritis (TA) is a chronic inflammatory large-vessel arteriopathy involving the aorta and its major branches and may result in cerebral ischemia due to arterial stenosis or thrombosis. Case Presentation: We report the case of a 26-year-old woman with a history of suspected rheumatoid arthritis and Lyme disease who presented with acute left-sided hemiparesis and dysarthria. At admission, large-vessel vasculitis had not yet been suspected, and the patient was treated according to standard acute stroke protocols. Computed tomography angiography (CTA) revealed occlusion of the right middle cerebral artery bifurcation and the right common carotid artery, with inflammatory changes involving the brachiocephalic trunk and subclavian arteries. Intravenous thrombolysis (iv rtPA) was followed by mechanical thrombectomy (MT), resulting in neurological improvement. Outcome: Further diagnostic work-up confirmed TA, and immunosuppressive therapy with cyclophosphamide and infliximab was initiated. Conclusion: This case underscores the importance of considering inflammatory large-vessel disease in young patients presenting with acute ischemic stroke and illustrates that endovascular reperfusion may be feasible in this clinical setting.
