Common manifestations when Giant Cell Arteritis involves extracranial distributions
Giant Cell Arteritis can involve both large- and medium-sized arteries. Pulmonary artery involvement is unusual. Involvement of the subclavian, vertebral, carotid, iliac, mesenteric, and renal vessels may lead to various manifestations, including pulse abnormalities, stroke, dizziness, claudication, abdominal pain, and hypertension in some instances. Coronary involvement can lead to anginal symptoms.
Pearl: vertebral artery abnormalities are more likely due to GCA than atherosclerosis.
