ABSTRACT
Ultrasound diagnosis of a lateral ventricle choroid plexus cyst was made in a 20-week
gestational age fetus. The cyst remained visible until the 34th week, after which
it spontaneously resolved. Persistence of such cysts beyond 23 weeks has been suggested
as a poor prognostic sign by some investigators. The importance of serial ultrasound
evaluation and fetal karyotyping is discussed.
