Is it a specific abnormality which may indicate non-viability?
Choroid plexus cyst is a benign finding, and considered a soft marker. Unless associated with other malformations, it may be disregarded as a non-alarming finding, yet it should be monitored for its size antenatally and postnatally.
An anechoic lesion is noted in left choroid plexus.
No other abnormality is noted during fetal anatomical survey.
