Prenatal diagnosis of intrauterine fetal goiter a rare case report

Abstract

The incidence of fetal goiters is rare and can have poor neonatal outcomes due to tracheal and esophageal obstruction. This makes prenatal diagnosis and treatment pertinent. We report a case of a 25-year-old fifth gravida diagnosed with a large solid homogenous bilobed hypervascular mass noted on the anterior of the fetal neck, causing hyperextension of the cervical spine. A Fetal MRI was performed which revealed intermediate to hyper intensity on T2 weighted image, which were consistent with fetal goiter. The fetus was delivered at 38 weeks of gestation, and the intrapartum and postpartum period was uneventful. Postnatal TSH FT3 and FT4 were done which were consistent with hypothyroidism. With appropriate treatment, the size of the thyroid gland was observed to decrease. The neonate was found to be doing well postnatally.
