Thyroid hemiagenesis represents a congenital disorder characterized by the absence of development of one of thyroid lobes, associated or not with absence of isthmus. It is more frequent in women and generally presents as absence of the left lobe, with compensatory hypertrophy of the contralateral lobe. Its diagnosis is generally incidental or by manifestations of the present thyroid lobe. A bibliography review was made, where no cases reported in Venezuela of hemiagenesis or thyroid agenesis were found, describing the following. We present a 50-year-old patient, known with hypothyroidism since she was 31, denying any surgery in the head and neck area. Since February 2019, presented a progressive increase in volume in the anterior neck region. On physical examination, an increase in volume was observed in right anterior region of the neck, palpating an enlarged right thyroid lobe, with a nodular appearance and not painful. In a thyroid echo-sonogram, it was concluded as a right thyroid goiter with a multinodular appearance, with the absence of the left lobe. Thyroid profile within normal limits. It is taken to the operating table, confirming the absence of the left lobe and presented in the definitive biopsy nodular hyperplasia in the right lobe. Its frequency, form of presentation, and literature review are discussed(AU)
