Granulomatous giant cell arteritis (GGCA) (Horton disease) can damage all medium and large arteries. Clinical manifestations are found fundamentally in branches of the carotid artery, and it is currently accepted that the aorta and its main branches are always affected, although they do not show symptoms.1 Small-vessel vasculitis is considered exceptional. When this occurs, it is important and sometimes difficult to differentiate it from other types of granulomatous vasculitis. We report a case of GGCA that, along with the typical manifestations of headache, jaw claudication, and loss of vision, also had associated pulmonary, cutaneous, muscular, peripheral nervous system, and cranial nerve effects.
