GRANULOMATOSIS WITH POLYANGIITIS PubMed ID:http://jpet.aspetjournals.org/content/183/2/433 (RN-1734 manufacturer Wegener’s) The aetiopathogenesis of granulomatosis with polyangiitis is unknown and most likely multifactorial; ANCAs surely possess a essential function in vascular inflammation pathogenesis.

The nodular lesions are frequently related for the vessels, and they usually involve mainly thesubpleural regions but have no predilection for the upper or reduced lung zones. The presence of a rim of groundglass opacity around the nodules (halo sign) is frequent and would be the expression of alveolar haemorrhage (Figure ); the presence of an air bronchogram within pulmory nodules is equally common (Figure ). Just after therapy, the lesions typically show a slow resolution characterized by a marked wall thinning (Figure ).
