Abstract

Chronic invasive fungal sinusitis is a slowly destructive process that most commonly affects the ethmoid and sphenoid sinus, but may involve any paranasal sinus. The disease typically has a time course over 12 weeks. Pathologically, it is characterized as a dense accumulation of hyphae, occasional vascular invasion and sparse inflammatory reaction with involvement of local structures. Aspergillus fumigates is the most common pathogen. In this report, we present a patient with chronic invasive fungal sinusitis invading pterygopalatine fossa, which was presented as only mild thickening of posterior wall of maxillary sinus at initial CT scan.
