Approach

Establishing the diagnosis of Takayasu's arteritis can be difficult, as it may present with non-specific systemic symptoms including fever, night sweats, and weight loss. Other presenting features may include ischaemic symptoms of extremity claudication, transient ischaemic attack, stroke, or chest pain. Laboratory tests are non-specific, reflecting inflammation. Biopsy of involved vessels is not usually feasible, and the diagnosis relies on vascular imaging.[1][2][7]
