An Unusual Presentation of Giant Cell Arteritis Mimicking Stroke: A Case Report with Clinical Images

Abstract

Giant Cell Arteritis (GCA) is a systemic vasculitis that primarily affects medium and large arteries, predominantly in older adults. Although classic symptoms include headache, jaw claudication, and vision disturbances, GCA can present atypically, leading to diagnostic challenges. We report a rare case of GCA mimicking an acute ischemic stroke in a 72-year-old female who presented with sudden-onset unilateral weakness and dysarthria. Initial neuroimaging ruled out cerebral infarction, prompting further vascular assessment. Temporal artery biopsy confirmed the diagnosis of GCA, and the patient responded well to corticosteroid therapy. This case highlights the importance of considering GCA in the differential diagnosis of stroke-mimicking syndromes, especially in elderly patients, to prevent irreversible complications. The report includes detailed clinical images illustrating key diagnostic findings.
