Patients with thyroid disease may present with local signs such as a palpable diffuse (goiter) or focal (nodular) enlargement of the gland and/or with systemic symptoms due to endocrine disturbance resulting in altered metabolism (hyperthyroidism or hypothyroidism). While physiological derangement is well assessed by clinical examination and laboratory biochemical tests, the evaluation of the structural anomaly relies heavily on modern ultrasound imaging which provides high-resolution anatomical details of any morphological alteration.
