Fetal Goiter
Pronunciation: GOY-ter
Enlargement of the fetal thyroid gland visible on prenatal ultrasound, potentially affecting delivery and neonatal care.
Full Definition
Fetal goiter refers to enlargement of the fetal thyroid gland that can be detected through prenatal ultrasound examination. This condition may result from maternal hyperthyroidism, hypothyroidism, or exposure to antithyroid medications, iodine deficiency, or genetic factors affecting thyroid hormone synthesis. Fetal goiters appear as symmetric or asymmetric neck masses that can compress the trachea and esophagus, potentially leading to polyhydramnios due to impaired fetal swallowing. Large goiters may cause hyperextension of the fetal neck, complicating vaginal delivery and requiring cesarean section or specialized delivery techniques.
Usage
Usage note: Two words when referring to fetal condition; one word for the general medical term.
