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). Electron microscopy of the cyst wall may support its neuroepithelial character by showing typical intercellular junctions, called zonulae adherentes, cilia (common in ependymal but rare in choroid plexus cysts), microvilli, and pinocytotic vesicles (28; 30). However, the majority of studies quote a diameter greater than 3 mm to be significant16-19. At least two orofaciodigital syndromes (I and II) may harbor this combination, and it has also been found as part of Aicardi syndrome (11).
