TLDR THA is a rare condition with no significant clinical consequences if thyroid function is normal.

The document discusses hemiagenesis of the thyroid gland (THA), a rare congenital condition where one thyroid lobe and sometimes the isthmus are absent. It presents a case of a 21-year-old male who exhibited symptoms such as hair loss, fatigue, and concentration problems, which led to a suspicion of hypothyroidism. Despite normal thyroid function, a sonography revealed the patient had THA of the left lobe and the isthmus. The document reviews the current understanding of the development and clinical implications of THA, drawing on existing literature.
