Thickening of the fetal nuchal fold associated with chromosomal abnormalities is termed what?

Explanation:
Thickening of the fetal nuchal fold is called nuchal edema. This finding indicates increased tissue fluid in the neck region and is associated with a higher risk of chromosomal abnormalities such as trisomy 21. It’s important to distinguish it from nuchal translucency, which is a fluid-filled space behind the neck measured in the first trimester for risk assessment; the term in this context refers to actual fold thickening, hence edema. The other options describe unrelated neck findings and do not reflect this chromosomal risk marker.
