Ex Utero Intrapartum Treatment (EXIT) for a Large Fetal Neck Mass.

Abstract

A 23-year-old primigravida was referred to our hospital at 36 + 5 weeks gestation with scan showing gross polyhydramnios and fetus having a large neck mass. She had no antenatal risk factors. An anomaly scan done at 22-week gestation was told to be normal. Repeat scan done here showed gross polyhydramnios with the amniotic fluid index (AFI) being 44 cm. The fetus was growth restricted with an estimated fetal weight of 1.8 kg. There was a 8 × 6 cm left anterolateral mass on the fetal neck, which was solid, well defined with minimal vascularity (Fig. 1). There seemed to be no retrosternal extension of the mass. There was no other structural abnormality to account for the fetal growth restriction (FGR) with polyhydramnios. Her glucose tolerance test at fifth month was normal.
