Abstract
|
|
|
|
Thyroid hemiagenesis is a rare congenital anomaly in which one thyroid lobe fails to develop. Thyroid hemiagenesis usually does not cause clinical symptoms by itself, therefore, this anomaly is detected incidentally during the evaluation of other thyroid disorders. We describe a rare case of thyroid hemiagenesis in a 1-month-old female infant who presented with prolonged jaundice and abnormal laboratory findings of congenital hypothyroidism. The patient showed the characteristic features of thyroid hemiagenesis of the left lobe in Tc-99m pertechnetate scintigraphy and ultrasonography of the thyroid gland. The patient has improved with supportive care, including thyroid hormone replacement. Further long-term follow-up is required for the investigation of recurrence of thyroid abnormalities.
