Development of nuchal translucency[ edit ] The actual anatomic structure whose fluid is seen as translucency is likely the normal skin at the back of the neck, which either may become edematous or in some cases filled with fluid by dilated lymphatic sacs due to altered normal embryological connections.

So after this time any abnormalities causing fluid accumulation may seem to correct themselves and can thus go undetected by nuchal scanning. The buildup in fluid is due to a blockage of fluid in the developing fetal lymphatic system.
