Isolated Increased Nuchal Translucency With Normal Chromosomal Study: A Case Report.

ABSTRACT

Increased nuchal translucency (NT) leads to a higher risk of fetal structural abnormalities. The measurement between 11 and 14 weeks gestation is a reliable marker for associated chromosomal abnormalities. Here, we present the case of a 33-year-old female with isolated high NT in the range of 5.6 mm at 12 weeks of gestational age. She was evaluated for chromosomal and structural abnormality and followed up meticulously. None of the tests showed any chromosomal or obvious structural abnormality. Fetal echocardiography revealed no structural cardiac defect. The pregnancy was uneventful and she delivered a healthy baby at term through lower (uterine)-segment cesarean section. The baby girl is living in good health without any developmental abnormalities. Although there is a high risk of chromosomal/structural defects with increased NT, it is not mandatory to terminate the pregnancy without a thorough evaluation.
