Differentiating pulmonary cavities.

We present the case of a patient with pulmonary cavitation of extremely unusual aetiology, which presented a significant diagnostic challenge despite multidisciplinary involvement. A 54-year-old male presented with a 6-week history of haemoptysis associated with fatigue, night sweats and dyspnoea. His past medical history was significant for coronary artery stenting (treated with aspirin). There was no history of exposure to tuberculosis. He had a 50-pack-year smoking history, prior excessive alcohol consumption and had worked in construction, though denied asbestos exposure. On physical examination, vital signs were normal, his dentition was poor, there was no digital clubbing and chest auscultation was unremarkable.
