Hyperattenuating material in the paranasal sinuses can be due to hemorrhage, inspissated secretions, or mineral accumulation by fungi. The total IgE level of this patient was 4549 KIU/L. The imaging findings and increased total IgE level are suggestive of allergic fungal rhinosinusitis. There is no evidence of invasive fungal disease (such as bone destruction or obliteration of fat planes).
