Answer (1 of 5): Down syndrome occurs when there is an extra chromosome in trisomy number 21 (3 chromosomes where there should be only 2). In this article, the author, whose special interest is in developmental and genetic disorders, reviews the present knowledge of ependymal cysts and also addresses a related entity, the choroid plexus cyst. Choroid plexus cysts arise from choroid plexus in any of the ventricles and are loculated cysts with the secretory epithelium facing outward into the ventricular cavity or inward to the cyst lumen. Most MCDK are unilateral, with the left kidney more often affected (53.1%) [2]. We describe two cases of agenesis of the corpus callosum (ACC) with interhemispheric cyst (IHC). Each of us has 46 chromosomes that pass the genetic code from cell to cell. Echogenic intracardiac focus. Cleft lip and cleft palate, also known as orofacial cleft, is a group of conditions that includes cleft lip, cleft palate, and both together. Blake pouch cysts are expansions into the fourth ventricle as an embryonic remnant of ballooning of the superior medullary velum, resulting in an avascular ependymal-lined cyst protruding into the cisterna magna. Baltimore: Williams & Wilkins, 1996:224-31. An indication for amniocentesis? The origin of epithelial cysts may be difficult to determine on the basis of their routine histological aspect alone. Finally, ear length at 11-14 wk of gestation has been evaluated in screening for chromosomal defects but the degree of deviation from normal is too small for this measurement to be useful as a marker for trisomy 21 [ 51 ].

Case report with review of the literature. Case 1: a male infant was born at 36 weeks gestation with a history of second trimester fetal ultrasound (US) scan and MRI showing ACC with IHC. The latter finding led these authors to suggest that ependymal cysts expand through active secretion of its cells, rather than by passive diffusion. Am J Med Genet 1987;27(4):977-82.
