Objective: To study the incidental abnormalities of paranasal sinuses in cancer patients who underwent F18-FDG PET/ CT scan. Methods: Study population was 342 patients who presented at Armed Forces Institute of Radiological Imaging (AFIRI), Rawalpindi from December 2019 to March 2020, out of which 101 patients showed CT findings with F18-FDG avidity in paranasal sinuses. Findings were Mucosal thickening, retention cyst and opacification seen in either one or multiple sinuses unilaterally or bilaterally. Mucosal thickening and opacification were labelled as active disease while retention cyst as non-inflammatory. Maximum standardized uptake values (SUV Max) of all the involved sinuses on PET were calculated to assess correlation between CT and PET findings. Results: 101 out of 342 (29%) patients who underwent PET/CT for oncological purpose had abnormal incidental findings in paranasal sinuses with maxillary sinus being the most commonly involved. The best cut-off value for sinusitis on PET/CT was calculated to be 1.82 with specificity of 90.8% implicating that SUVs above this cutoff value will likely represent sinusitis Conclusion: From the findings of this study, it can be concluded that incidental sinus findings are not seen uncommonly in cancer patients.
