Case Discussion

Granulomatosis with polyangiitis (GPA) is a multisystem necrotising non-caseating granulomatous vasculitis involving the small to medium-sized arteries, capillaries and veins. It most commonly affects the respiratory system and kidneys as in this case.

This patient also had laboratory evidence of renal impairment and a renal biopsy identified concurrent renal involvement.

Four types of pulmonary involvement are recognised as one of which is typified by peripheral wedge-like consolidation. as illustrated in this case.

The post lung biopsy haemoptysis self-resolved.   Immunosuppressive treatment was commenced.
