Nuchal translucency

Case contributed by Dr Henry Knipe

Presentation

Combined first trimester screening.

Patient Data

Age: 36 years
Gender: Female
Ultrasound

CRL is 56 mm. Nuchal translucency is 2.1 mm. 

The expected nuchal translucency (NT) is 1.54 mm (50th percentile) - the measured NT value is 84th percentile for this CRL.

Case Discussion

Increased nuchal translucency (>95th percentile) is indicative of abnormal chromosomes (e.g. aneuploidy) and in the absence of this, it is still associated with increased risk of structural abnormality (e.g. major cardiac defects).

A more accurate risk assessment can be obtained when this measurement is combined with serum markers and maternal age.
