Chronic rhinosinusitis

Discussion:

The radiological features are reflecting chronic changes of rhinosinusitis. Bone sclerosis and demineralization can occur simultaneously in the setting of chronic sinusitis 1. Bony changes of chronic sinusitis include decreased sinus size, hyperostosis and occasionally bone demineralization if there is associated pathology like fungal infection and sinonasal polyposis.

Features of associated chronic rhinitis include roomy nasal cavities, resorption of ethmoid bulla and uncinate process, hypoplastic maxillary sinuses, erosion and bowing of lateral nasal walls.
