Listen to MedLink on the go with Audio versions of each article. Whereas ependyma lining the ventricles are a pseudostratified columnar epithelium during much of fetal life, becoming thinned to a simple epithelium 1 cell thick as the brain grows and the ventricles enlarge, increasing their surface area, choroid plexus exhibits simple cuboidal epithelium throughout fetal life, being stratified only very transiently at the beginning of its formation at about 3 to 4 weeks of gestation in the fourth ventricle and 5 to 6 weeks in the roof of the third ventricle and lateral ventricles. . Echogenic intracardiac focus and choroid plexus cysts are common findings at the midtrimester ultrasound. These findings have been linked with an increased risk of Down syndrome and trisomy 18.

Orofaciodigital syndromes, originally defined on the basis of phenotypical features and genetic transmission patterns, have been reordered on the basis of genomic mutations found in a large cohort (13). They usually are not permanent (the feature will usually disappear later in pregnancy). Clinical interest in ependymal cysts centers on two different entities: (1) Solitary ependymal cysts arising as space-occupying cysts with clear fluid. WebChoroid Plexus Cysts. The importance of the clustering of markers forms the basis of the scoring index, such that individual markers are assigned point values based on their sensitivity and specificity in the detection of Down syndrome.
