Chronic invasive fungal sinusitis: characterization and shift in management of a rare disease

Abstract

CIFS is an insidious disease often with months between symptom onset and diagnosis. It is differentiated from chronic granulomatous invasive fungal sinusitis (CGIFS) by a lack of granulomas on histopathology and an association with diabetes mellitus. Endoscopic debridement combined with long-term oral voriconazole was an effective treatment strategy in this series.
