ABSTRACT
Thyromegaly is defined as enlargement of the thyroid gland. The term goiter refers to any thyromegaly, diffuse or nodular, and the term simple goiter (or nontoxic goiter) describes goiter that is not associated with thyroid dysfunction or autoimmune thyroid disease (1,2). Thyromegaly can involve the entire gland (diffuse thyromegaly) and/or result from thyroid nodules (nodular thyromegaly). Types of thyromegaly can be classified according to cause (Table 1).
