AN UNUSUAL CAUSE OF RENAL FAILURE

A 58-year old female, a known asthmatic, presented with acute breathlessness for 1 week, and was found to have acute kidney injury. Renal biopsy revealed pauci-immune necrotising glomerulonephritis and necrotising vasculitis. She was positive for P-ANCA, and a diagnosis of ANCA-associated vasculitis with rapidly progressive glomerulonephritis was made.
