What are the two types of large vessel vasculitis?
Temporal (Giant cell) Arteritis and Takayasu Arteritis
Name the vasculitis — granulomatous vasculitis; branches of carotid artery; older adults >50; females; presents as HA, visual disturbances and jaw claudication; flu-like symptoms with joint and muscle pain
Temporal (Giant Cell) Arteritis
Biopsy of Temporal Arteritis reveals?
inflammed vessel wall with giant cells and intimal fibrosis

Corticosteroids
What are the 3 types of medium vessel vasculitides?
Polyarteritis Nodosa, Kawasaki Disease, Buerger Disease
Name the vasculitis — necrotizing vasculitis involving many organs but spares lungs; presents as HTN, abdominal pain with melena, neurologic disturbances and skin lesions; HBsAg; fibrinoid necrosis; “string of pearls”
