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. Choroid plexus cyst WebChoroid plexus tumors grow into the ventricles (fluid-filled spaces in the brain) from the cells that produce spinal fluid. Ependymal cysts may be space occupying, either by displacement of adjacent structures or by obstructing CSF circulation. Radiology Each of us has 46 chromosomes that pass the genetic code from cell to cell. 1 0 obj Ependymal cysts are immunoreactive for glial fibrillary acidic protein (GFAP) and S-100, both glial markers expressed by normal immature ependymal epithelium. However, the majority of studies quote a diameter greater than 3 mm to be significant16-19. Web2) Choroid Plexus Cyst (CPC) A choroid plexus cyst is a small collection of fluid in the part of the brain called the choroid plexus. Larger CPCs have been described rarely, with normal neurological outcome reported 3. Transitory expression of vimentin and S-100 protein occurs in fetal ependymal and choroid plexus epithelial cells, but glial fibrillary acidic protein is expressed only in fetal ependyma and never in choroid plexus epithelium (62; 63). Surg Neurol 1976;(3):181-4. The improvement in neurosurgical techniques underlines the need for refined differential diagnosis, separating this group from malignant cystic tumors such as cystic gliomas.

The widespread use of sonographic markers, such as echogenic intracardiac focus (EIF) or choroid plexus cyst (CPC) to assist in identifying fetuses at increased risk for common aneuploidies. In the first type of choroid plexus cyst, it is not as easily explained why the cyst should enlarge by accumulating more fluid, but the same occurs in many cases or the cyst is more likely to persist into postnatal life beyond the neonatal period.
