Microscopic polyangiitis is a small vessel vasculitis, associated with myeloperoxidaseantineutrophil cytoplasmic antibody. It rarely occurs in children. Central nervous system involvement in pediatric microscopic polyangiitis is not a well known entity with perhaps only five cases till date. We hereby present a 14-year-old girl with arthralgia, seizure, leukocytoclastic vasculitis, interstitial lung disease secondary to recurrent pulmonary hemorrhage, pauci-immune glomerulonephritis and high titers of MPO-ANCA, hence diagnostic of microscopic polyangiitis. Magnetic resonance imaging of brain showed diffuse parenchymal involvement which resolved at six months with development of new foci of microhemorrhages in different stages of evolution, reminiscent of vasculitis..
