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 ]. Antenatal choroid plexus cysts are benign and are often transient typically resulting in utero from an infolding of the neuroepithelium. Successful endoscopic surgery or endoscope-assisted keyhole surgery has been reported in a series of intraparenchymal ependymal cysts of the mesencephalon causing Parinaud syndrome or hydrocephalus (19) or intraventricular cysts, enabling communication of the cyst with the subarachnoid fluid (24) or cyst fenestration (02; 04).
