Introduction: The clinical spectrum of thyroid nodules vary from an incidental and asymptomatic nodule, in 59 which cancer is the major concern, to clinically relevant nodules (= 1 cm) with compressive symptoms. This 60 study aims to compare clinical, ultrasonographic and cytological features of thyroid incidentalomas with 61 Materials and Methods: This cross-sectional retrospective study included 812 patients with thyroid 62 nodules, who underwent thyroid ultrasonography and Fine Needle Aspiration from January 2007 to 63 December 2013. We collected clinical and sonographic characteristics, and cytology was expressed 64 according to the Bethesda classification. Results: Of the 812 patients, 32.1% presented incidentalomas (< 1 65 cm). Thyroid incidentalomas presented as solid hypoechogenic and with peripheral vascularization lesions, 66 while nodules = 1 cm were mixed, hyperechogenic, with central and peripheral vascularization. Bethesda I 67 class was most commonly found among incidentalomas, and Bethesda II in the clinically relevant nodules’ 68 group. The frequency of malignant cytologies (Bethesda V and VI) was low in both groups. Conclusion: 69 Despite the ultrasound characteristics found in thyroid incidentalomas, they did not present a higher 70 frequency of suspicious or malignant cytologies. Instead, insufficient results were more frequent in this 71 group, which reinforces the current tendency to value suspicious sonographic characteristics altogether and 72 consider the possibility of follow-up of subcentimetric nodules.
