A 65-year-old woman underwent a chest computed tomography scan that revealed infiltrative shadows on the right upper lobe and multiple nodules on the left upper and lower lobes, one month after she had suffered from a moderate case of coronavirus disease 2019 (COVID-19). Her blood tests were positive for myeloperoxidase anti-neutrophil cytoplasmic antibodies, and renal failure had developed. Renal biopsy revealed necrotizing and crescentic glomerulonephritis and she was therefore diagnosed with granulomatosis with polyangiitis. Rituximab treatment and steroid pulse therapy were initiated, which provided effective results. The onset of vasculitis after COVID-19 is not predictable from the disease severity of the COVID-19.
