Background: Our study investigated the diagnostic value of the mineralization findings and high-density secretion features of sinus computed tomography (CT) images in cases of chronic rhinosinusitis (CRS) compared to histopathology and operative findings. Methods: This was a prospective cohort study of 193 patients consecutively enrolled for endoscopic sinus surgery (ESS). Group 1 had mineralization in the sinus; group 2 had high-density secretions in the sinus but no mineralization; group 3 lacked both high-density secretions and evidence of mineralization. Intergroup comparisons were performed for histopathology (especially presence of fungus ball), CT scores, and gross operative appearance. Results: Histopathologic evidence of fungus ball (FB) compared to presence of CT findings was significantly different between the groups, with the following percentages of patients demonstrating FB presence: 33% of group 1 (CT mineralization) (n = 48); 4% of group 2 (CT hyperdensity) patients (n = 25); and 2% of group 3 (no mineralization, no hyperdensity) patients (n = 120) (p < 0.05). Operative findings did not necessarily correlate with CT findings and all groups demonstrated varying amounts of dry cheesy (DCM) or wet clay-like (WCLM) material, though this was slightly higher in groups 1 and 2. Conclusion: A preoperative survey of sinus mineralization and high-density secretion features observed with CT was predictive of operative findings and histopathological results indicating a sinus FB.
