Fungal sinusitis

Fungal sinusitis includes non-invasive types like fungal ball and AFRS, and invasive forms such as acute and chronic invasive disease. AFRS occurs in immunocompetent atopic patients with nasal polyps, while invasive forms affect immunocompromised hosts, causing rapid tissue invasion and complications. Diagnosis uses endoscopy, imaging, and histology. AFRS is managed with surgery and steroids, while invasive cases require urgent debridement, antifungals, and immune recovery.
