Background and Aim: Thyroid nodule which is not detected by palpation but is diagnosed following a radiological procedure or during surgery is called thyroid incidentaloma. This study was designed to investigate prevalence of sonographic thyroid incidentaloma in Isfahan in 2006. Materials and Methods: In this cross-sectional study, 2523 adults were randomly selected through cluster sampling method. 2045 of them had normal thyroid examination results 234 of these were randomly selected for thyroid sonography. Their thyroid stimulating hormone (TSH) and urinary iodine concentrations (UIC) were measured. Results: Prevalence of thyroid incidentaloma was 13.2%. Age of people with and without incidentaloma was 46.1±12.4 and 38.4±12.1 respectively (P=0.002). The prevalence was higher in females than males (19% vs. 10%, P=0.002). Labor frequency in women with thyroid incidentaloma was higher than that of the healthy group (93.7% vs 58.8%, P=0.001). Levels of TSH were not different in the two groups. Median UIC in incidentaloma group (14 µg/dL: 2-40) was significantly lower than that in the healthy group (20 µg/dL: 1.8-42), (P=0.02). Mean diameter of nodules was 8.14±3.43 mm. Conclusion: Prevalence of thyroid incidentaloma was 13.2% in Isfahan. This is similar to obtained results in other communities. The disorder was higher in females than in males and increased with age.
