Abstract

Purpose: The aims of this study was to analyze the characteristics of intra-sinus calcification on computed tomography (CT scan) in the diagnosis of fungal sinusitis. Material and Methods: Descriptive study on 70 rhinosinusitis patients examined at Hanoi Medical University Hospital from January 2022 to July 2023. These patients were all underwent a CT scan of the sinuses, then endoscopic sinus surgery and diagnosis confirmed by post-operative fungal testing. Results: Mean age was 53±11.8, the lowest age was 30 years old, the highest age was 78. Fungal sinusitis was diagnosed in 60/70 patients, accounting for 86%, of which 46/60 patients were sinus mycosis, accounting for 76.7%, the remaining was chronic invasive fungal sinusitis. On CT scan, the most common location of calcification was in the center of the sinus, accounting for 84.9%, calcification at the periphery was only seen in 11.3% of cases, this difference was statistically significant with p<0.01. In the group of fungal sinusitis patients, the most common calcification morphology was line-shaped, accounting for 69.8%, the least common was round, eggshell, accounting for 3.6%. The location of calcification in the non fungal sinusitis group was mainly found in the periphery (75%), the difference was statistically significant with p<0.01. The sensitivity, specificity, accuracy, positive predictive value, negative predictive value of calcification signs in the opacities in diagnosing fungal sinusitis were Sn=88.3%; Sp=20%; ACC=78.6%, PPV=86.9%, NPV=22.2%, respectively. Conclusion: intra-sinus calcification on computed tomography had a high value sign for diagnosing fungal sinusitis.
