ABSTRACT

An 83-year-old male had been treated for Mycobacterium kansasii pulmonary infection with isoniazid, rifampicin and ethambutol. Although Mycobacterium sp. had never been detected in several sputa in the course of a 19-month treatment, a chest computed tomography (CT) showed cavity wall thickening in the right upper lobe. Cunninghamella bertholletiae was identified in both sputum and bronchoscopic specimens, and consequently we diagnosed pulmonary mucormycosis. He has undergone no antifungal treatments for more than a year; nevertheless, the chest CT findings remained almost the same. This is the first case report of saprophytic pulmonary mucormycosis by C. bertholletiae. Radiological findings of saprophytic pulmonary mucormycosis are very similar to those of aspergillosis, so we should try to detect the etiologic agent when we diagnose them.
