Unusual rhinosinusitis caused by Curvularia fungi.



A variety of fungal diseases can affect the sinonasal cavities. Aspergillus fungus is the most common sole pathogen or copathogen, occurring in approximately 87% of cases. (1) Curvularia infection of the sinonasal area is rare.

We evaluated a 48-year-old black man who had a history of recurrent craniofacial dematiaceous infection of many years' duration. He had previously been evaluated at various institutions and treated with surgical debridement, irrigation, and antifungal therapy. He was suspected of having a natural-killer-cell deficiency. At presentation, he reported pain and exhibited a diffuse soft-tissue swelling of the sinonasal area. No evidence of infection in other organs was noted.

Computed tomography (CT) of the sinonasal area revealed extensive bone destruction in the maxillary and nasal cavities secondary to chronic infection with osteomyelitis (figure 1). Magnetic resonance imaging magnetic resonance imaging (MRI), noninvasive diagnostic technique that uses nuclear magnetic resonance to produce cross-sectional images of organs and other internal body structures.  (MRI) demonstrated diffuse inflammatory soft tissues in the facial and sinonasal areas (figure 2). Histologic findings and culture analysis identified a mycotic mycotic /my·cot·ic/ (mi-kot´ik)
