We present a 57-year-old male who presented with abdominal pain and was found to have a complex right renal lesion on abdominal imaging.

He was started on rituximab and steroids with dramatic improvement. Kidney biopsy revealed crescentic and necrotizing glomerulonephritis associated with ANCA-associated vasculitis.
