Abstract

Purpose: The aims of this study to evaluate the value of sinus opacities on computed tomography (CT scan) in diagnosing 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 all underwent a sinus CT scan and then a sinus endoscopic surgery and confirmed diagnosis by post-operative fungal testing. Results: Average 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 images of opacities in the sinus lumen were mainly heterogeneous opacities (98.3%), completely occupying the sinus lumen (80%). The rate of heterogeneous opacities in the fungal sinusitis group was higher than the non fungal sinusitis group, the difference was statistically significant with p<0.05. There was no statistically significant difference in opacification size between the two groups fungal and non fungal sinusitis. The sensitivity, specificity, accuracy diagnosis, positive predictive value, negative predictive value of the complete and heterogeneous opacification sign in diagnosing fungal sinusitis was Sn=80%; Sp=20%; ACC=71.4%, PPV=85.7%, NPV=14.3%. Conclusion: The sign of completely heterogeneous sinus opacities on computed tomography has high value for the diagnosis of fungal sinusitis.
