ANCA vasculitis (Anti-Neutrophilic Cytoplasmic Autoantibody) is a type of autoimmune disease that causes vasculitis.
Antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV)
is a group of diseases (granulomatosis with polyangiitis, eosinophilic granulomatosis with polyangiitis and microscopic polyangiitis), characterized by destruction and inflammation of small vess.
CT scan of a 67 year old female with anca vasculitis shows regions of dystrophic calcification in the lateral aspect of the right lower lobe (white arrow, a and b) )with focal nodular parenchymal consolidation, that likely reflects a site of prior small vessel infarct. Dystrophic calcification in the LV myocardium (blue arrows c) and a suggestion of fatty dysplasia in the left ventricular apex red arrow d) suggest changes from small vessel infarct.
