HIV-associated vasculitis rarely involves the aorta. There is no well-established association of HIV and giant cell arteritis. We present the case of a 31-year-old HIV positive Indian woman who was referred to us with complaints of dyspnea and chest pain. Physical examination revealed a diastolic murmur in the aortic area and echocardiography showed a dilated aortic root causing severe aortic regurgitation. She was being adequately treated with anti-HIV therapy. She underwent aortic valve and root replacement and the histopathological findings of the aortic specimen showed giant cell arteritis.
