Methods: The CT reports were retrospectively reviewed to evaluate IFs. Cases were divided into five age-groups (0–19, 20– 39, 40–59, 60–79,≥80). IFs were classified as "Group 1": congenital anomalies that do not require further investigation, non-degenerative/minor degenerative findings; "Group 2": findings that do not require immediate intervention, require outpatient follow-up/in case of symptoms; and "Group 3": findings that require immediate intervention/further investigation. Results: There were 2385 CT scans and 1802 incidental findings (IFs) in 783 trauma cases. CT scans with IFs constituted 50.2%. The percentage of IFs was 75.6% in males and 24.4% in females, and they occurred in 4.8%, 27.6%, 44.3%, 20.9%, and 2.4% of age groups 1 to 5, respectively. Group 1 had 34.6%, group 2 had 54.6%, and group 3 had 10.8% IFs. There was not any significant association between the classification and gender or age-groups. In terms of organs, IFs of the thyroid and gall bladder & bile ducts were significantly higher among females (P=0.044 and P<0.001, respectively), while IFs in the head & neck region were significantly higher in males (P<0.001). Incidental findings in the kidney, liver, adrenal gland, and vascular structures differed significantly across age-groups (P<0.05). Conclusion: There were no significant relationships between the classification of IFs and gender or age-groups. However, the distribution of IFs was significantly associated with gender and age-groups in terms of organs. Healthcare professionals should consider this relationship when following up and treating patients.
