Abstract
Background The PNS sinuses are air filled cavities which are extensions of the nasal cavities. Various pathological processes affect these structures but inflammatory conditions are the commonest. Even in asymptomatic patients who undergo brain imaging for other indications show one or more incidental abnormalities in their sinuses. Objective of the study To determine the prevalence of incidental PNS abnormalities seen among patients who undergo Brain MRI scanning in of the private diagnostic centers in Addis Ababa. Methods Soft copies of brain MRI studies were collected from a private diagnostic center & the images were jointly examined by the investigator & the advising senior neuroradiologists at the radiology department of AAU. T2W axial images were mainly studied but additional coronal & sagittal images were also examined whenever needed. Result Of the total 115 patients, 66 were males & 49 females. From all, 62.2% showed abnormalities in at least one of their sinuses. Significant paranasal mucosal thickening of more than 3mm was the commonest finding followed by presence of polyps or retention cysts. The most involved sinus groups were the ethmoid & maxillary sinuses.
