A Rare Case of Takayasu Arteritis Presenting With Syncope and Elevated Inflammatory Markers in an Elderly Male With Learning Disability.

Takayasu arteritis (TAK) is a rare large-vessel vasculitis predominantly affecting young females. We present a unique case of a 77-year-old male with learning disability, presenting with constitutional symptoms, syncope, and elevated inflammatory markers. Imaging revealed circumferential thickening of the aorta and arch vessels, consistent with TAK. This case underscores the importance of considering large-vessel vasculitis even in elderly patients, as well as the diagnostic challenges in individuals with cognitive impairment. The patient responded well to corticosteroid therapy.
