Allergic fungal sinusitis (AFS) was recognized more than a decade ago, initially by Millar and Lamb1, 2 in Great Britain and subsequently by Katzenstein et al. This results from an inflammatory reaction to fungus in the sinuses. This reaction to fungus in the lungs can occur in people with asthma or cystic fibrosis. Conclusion . Mold spores are very light and are floating in the air. On unenhanced CT the sinuses are typically opacified by centrally (often serpentinous) hyperdense material with a peripheral rim of hypodense mucosa. Coronal CT scan showing typical unilateralappearance of allergic fungal sinusitis withhyperintense areas and inhomogeneity ofthe sinus opacification; the hyperintenseareas appear whitish in the center of theallergic mucin. It accounts for approximately 6% to 8% of all chronic sinusitis requiring surgical intervention and has become a subject of increasing interest to otolaryngologists and related specialists. Image studies show complete opacification of the left frontal sinus, left sphenoid sinus, and the left maxillary sinus. The fungal elements and allergic mucin in allergic fungal sinusitis always look hypointense on MRI scanning and can be mistaken for absence of disease. Allergic fungal sinusitis. Allergic fungal sinusitis (AFS) causes a relatively consistent configuration of disease. AFS is actually not an infection, but really an overzealous local immune response in the nasal and sinus tissue to exposure to mold. Allergic fungal sinusitis (AFS) was recognised as a distinct and separate clinical disorder for the first time in 1976 1 and it has become increasingly well-defined in the last couple of decades. A case of allergic fungal sinusitis (AFS) caused by Exserohilum rostratum, proven by culture and histopathology of the biopsy material, is described. 20. Reference Katzenstein, Sale and Greenberger 6 It has been estimated that this disease accounts for 5–10 per cent of all patients with chronic rhinosinusitis. This rare condition occurs when exposure to airborne particles such as mold spores causes the lungs to become inflamed. Clinical practice guideline (update): adult sinusitis. Allergic fungal sinusitis: incidence and clinical and pathological features of seven cases. It is increasingly recognized as a cause of chronic sinusitis, with the primary causative agents being members of the Dematiaceae fungus family. Allergic fungal sinusitis (AFS) is the most common form of fungal sinusitis and is common in warm, humid climates. Sinusitis, also known as rhinosinusitis, is inflammation of the mucous membranes that line the sinuses resulting in symptoms that may include thick nasal mucus, a plugged nose, and facial pain. The disease was first described my Millar and Associates in 1981 as allergic aspergillus sinusitis (1). Consequently, the disease process described only 15 years ago must be suspected to be diagnosed.

The entity was originally termed "allergic Aspergillus sinusitis" because of the similarity histopathologically to the entity of allergic bronchopulmonary aspergillosis (ABPA). A 59-year-old African-American man presented with right complete ptosis with ophthalmoplegia. Radical removal of all dead and infected tissue is necessary. Allergic fungal sinusitis is characterized by the presence of mucin, which is a combination of fungus and mucus that builds up in the sinus cavity and creates a blockage. Allergic bronchopulmonary aspergillosis. Since allergic fungal sinusitis was initially described by Millar in 1981, many have tried to define and explain the disorder. Allergic fungal sinusitis, a form of nasal allergy to environmental fungal elements resulting in the formation of allergic mucin and nasal polyps, is a common cause of sinus headache, nasal congestion, nasal discharge and other chronic sinusitis symptoms that do not respond to treatment with antibiotics.
