Sometimes these get stuck together and fluid collects between them, which appears as a cyst on ultrasound. However, ependymal cells themselves may also be positive for astroglial immunocytochemical markers. As with ependymal cysts, choroid plexus cysts also may rupture spontaneously into the surrounding CSF and, thus, disappear later in gestation or early in the postnatal period by ultrasonic or MRI examination.

On MRI, they may present as intraparenchymal, fluid-filled, space-occupying lesions, with a nonenhancing wall, which are usually situated close to the ventricular system, thereby causing intraventricular bulging (75). More than three malformations were found in 29% of cases (Figure 2).

Orphanet J Rare Dis 2014;9:74. . 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). The name cyst is sometimes applied erroneously to a midline ventricular diverticulum without true separation from the ventricular system, which can be found in holoprosencephaly or in Dandy-Walker syndrome. The screening test results have to be correlated with normal averages. Choroid plexus cyst As many as 2 percent of pregnancies will show choroid plexus cysts.
