Concha bullosa (CB) is a pneumatized air cell within the nasal turbinates, often in the middle turbinate. CB is one of the most common anatomical variations found in the middle turbinate. It generally tends to be asymptomatic but can cause symptoms such as nasal obstruction, facial pain, and a decrease in the sense of smell. Moreover, CB can be involved in chronic rhinosinusitis, which can lead to its confusion with other lesions, as the radiographic picture might mimic other nasal pathologies. Here, we report a case of massive CB involved with allergic fungal sinusitis (AFS) and mimicking a bony tumor in order to highlight the diagnostic challenge of this clinical entity.
Keywords: chronic rhinosinusitis; conchal pneumatization; mri; nasal polyposis.
