Wegener’s granulomatosis (WG) is an uncommon systemic vasculitis of unclear pathophysiology. We described
the case of a 53-year-old man diagnosed with WG characterized by necrotizing lung abscess. He was dissatisfied
with the lack of response to treatment of corticosteroids and antibiotics. With persistent fever and cough, he requested to
switch to Chinese herbal medicine (CHM) for further treatment instead. After two weeks of treatment, there was dramatic
improvement and both fever and coughing subsided. The chest X-ray film showed disappearance of air-fluid level, which
was compatible with the disease.
