The masquerade of vasculitis: head and neck diagnosis and management.

Wegener's granulomatosis and forms of giant cell arteritis result from vasculitis and masquerade with symptoms of common head and neck disease entities. Recognition of the manifestations of vasculitis can be made early in the disease course and confirmed pathologically, allowing effective therapy. Current therapy of Wegener's granulomatosis with Cytoxin and Imuran and steroids for giant cell arteritis frequently results in reversal of head and neck involvement, prevention of systemic disease, and prolonged survival.
