Multiple mycetomas due to Pseudallescheria boydii.

A patient with pulmonary sarcoidosis had evaluation of hemoptysis. A CT scan of the chest showed bilateral upper lobe cavities and five separate mycetomas with air-crescent signs. Bronchial washings were positive on stains for fungal elements, and all cultures grew Pseudallescheria boydii. We have not seen a previous report of multiple fungus balls due to P boydii demonstrated by chest CT.
