Introduction: The thyroid gland is fundamental to the body's homeostasis. Among the examinations used to evaluate the gland, ultrasound (US) is considered the most complete, in addition to being highly available and low-cost. Aim: To evaluate the presence and radiological characteristics of thyroid nodules in women treated at a medical specialty outpatient clinic. Method: This retrospective study evaluated data from women over 18 years of age who underwent thyroid US examination between January 2019 and July 2024. Results: Ultrasound examinations of 171 women, with a mean age of 57.91 years, were analyzed. Most were referred for compressive symptoms (29.47%) or previous nodules (29.47%). Approximately 44% of the glands presented normal morphology, while 30% showed volumetric increase. Thyroid nodules were frequent, with a predominance of hypoechoic types (44.9%) and TI-RADS patterns 3 (40.4%) and 4 (29.2%). Ultrasound proved essential for identifying structural changes and guiding biopsy. Conclusion: Thyroid nodules are common findings, and their prevalence may increase with age. This study reinforces the importance of ultrasound examination in clinical practice, especially as an initial method of investigation in symptomatic patients or those with risk factors.
