RESUMEN
Invasive fungal sinusitis is a rare, severe disease, most commonly presenting in immunocompromised patients who have impaired neutrophil function or who have received long term immunosuppressive therapy. The gold standard for treatment has been wide surgical debridement, intravenous administration of antifungal agents such as amphotericin B (AMB), and correction of the underlying immunocompromised state. A 51-year-old female was admitted to our hospital with fever and headache who had received renal transplantation 14 years ago in the other hospital. Paranasal sinus CT scan revealed hyperplasia and soft tissue density of the left maxillary sinus. Histological examination of the fungus ball and edematous mucosa of the left maxillary sinus revealed suspicious invasion of Aspergillus in the mucosa. Clinical improvement occurred after a combination of surgery and post-operative systemic antifungal therapy with voriconazole. We think that voriconazole as initial treatment may be initiated for invasive sinonasal aspergillosis, if the infection is known to be due to Aspergillus species.
