Community-acquired necrotising pneumonia caused by Panton-Valentine leucocidin-producing methicillinresistant Staphylococcus aureus

ABSTRACT

A 61-year-old male presented with community-onsetpneumonia not responding to treatment despite givenappropriate antibiotics. Computed tomography scan of thethorax showed large multiloculated pleural effusion withmultiple cavitating foci within collapsed segments; lesionswhich were suggestive of necrotising pneumonia. Drainageof the effusion and culture revealed methicillin-resistantStaphylococcus aureus, which had the same antibioticprofile with the blood isolate and PVL gene positive.
