Abstract

Introduction: To investigate the prevalence of incidental findings which were suspected as rhinosinusitis on computed tomography (CT) imaging of the brain and identify if there are any clinical correlations between CT abnormalities and patients’symptoms.

Methods: A descriptive and cross-sectional study of total 104 subjects who underwent CT brain for non-paranasal sinus related conditions. The CT findings were analyzed based on the Lund-Mackay scores by two blinded reviewers and the patients were divided into two groups according to their Lund-Mackay scores to compare differences between patients’ symptoms. The 22-question Sino-Nasal Outcome Test (SNOT-22) was completed if chronic rhinosinusitis symptoms were suggested.

Results: The prevalence of incidental paranasalsinus abnormality was 10.6%. The most common sinus abnormality was the maxillary sinus (41.3%), followed by anterior ethmoid sinus (19.2%) and posterior ethmoid sinus (15.4%). Patients’symptoms were not found to be significantly different between groups of normal and abnormal Lund-Mackay scores. Additionally, there was no significant correlation between Lund-Mackay scores and the SNOT-22 scores among the chronic rhinosinusitis patients (r = -0.18, P = 0.657).

Conclusions: The prevalence of incidental paranasalsinus abnormality was 10.6%. Incidental CT findings suggestive of rhinosinusitis may not correlate with symptoms.
