Thyroid nodules are common pathologies detected in thyroid gland. A thyroid nodule is the manifestation of a wide range of thyroid diseases, some benign and others malignant. Currently, the use of imaging methods has increased the diagnosis of asymptomatic nodules. Ultrasound studies of the population have reported a nodular thyroid disease rate of nearly 67% in elderly women. Most of these nodules are benign, and the incidence of malignancy is low (3–7%).
