Curvularia/Drechslera sinusitis.

Sinusitis due to unusual fungal pathogens is thought to occur primarily in immunocompromised individuals. However, the fungi Curvularia, Drechslera, and others produce sinusitis in healthy young adults. The signs and symptoms produced by these organisms are usually considered to be complications of sinusitis. Of the three cases that we report, two manifested decreased visual acuity, and the third presented with acute onset of seizures. Computed tomography scans were helpful in delineating the extent of disease and in following the results of therapy. Aggressive surgical treatment is necessary; indeed, two of our cases required a second operation to eradicate all disease. If histopathology shows tissue invasion by the fungus, intravenous amphotericin B is recommended. Fungal cultures and smears should be obtained when healthy patients present with complications of sinusitis.
