Thoracic Involvement in Polyangiitis Granulomatosis: A Moroccan Series of 21 Case

Granulomatosis with polyangiitis, formerly known as Wegener's disease, is a severe systemic necrotizing vasculitis, associating an inflammation of the vascular wall with a peri and extravascular granulomatosis. It is a rare disease that affects small vessels.it is classically translated by an otorhinolaryngological, respiratory and renal involvement. Other systemic manifestations of vasculitis may also be present.of slow evolution, the disease is often misleading and difficult to diagnose.The aim of our work is the analysis of the clinico-radiological thoracic and extra-thoracic manifestations, as well as the therapeutic and evolutionary profile in a retrospective study of a series of 22 cases.
