[Pleuropulmonary manifestations of systemic vasculitis]

Pleuropulmonary manifestations of systemic vasculitis are common, polymorphic and of ambiguous significance: the same pulmonary lesion may reveal a specific manifestation of vasculitis as well as a therapy-induced complication, especially infection which may favor per se a flare-up. Two questions will be successively studied: what are the pleuropulmonary characteristics of Wegener's granulomatosis, Churg-Strauss syndrome, periarteritis nodosa, Behçet's disease, Takayasu's disease and temporal arteritis? What are the major adverse effects that may occur in the course of a treated systemic vasculitis?
