Invasive aspergillosis occurs very rarely in immunocompetent hosts. We describe a 21-year-old female with no obvious immunosuppression or underlying lung disease, who presented with minimal symptoms and bilateral hilar prominence on chest X-ray. Invasive aspergillosis was diagnosed on an open lung biopsy. She deteriorated in the ensuing 2 weeks and died of a sudden massive haemoptysis. This initial radiological abnormality and the rapid clinical course of the disease in young immunocompetent patients have not been previously reported.
