With the exception of bowel echogenicity and choroid plexus cysts, the ultrasonographic markers have been found to be more common in fetuses with trisomy 21 than in euploid fetuses. It is difficult to propose a pathogenetic hypothesis of how these cysts might result in cognitive deficits and this report also requires further confirmation. Needle aspiration may be feasible for some cysts depending upon neuroanatomical location (03).

A layer of connective tissue on the outside may be present due to vascularization. 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). Webreborn as bonnie bennett wattpad choroid plexus cyst and eif together. These usually go away by the 28 th week, but can signal a chromosome defect. Open surgical resection is the traditional approach to both supra- and infra-tentorial cysts, but location of the cyst and proximity to the ventricles or subarachnoid space are paramount in selection of surgical approach (60).

The maternal fetal medicine doctor said they don't even like telling people about the echogenic focus being a marker because it is not a good indicator of a problem. According to some neurosurgeons, the approach to all expansive intracranial cysts, whether developmental or acquired such as posthemorrhagic cysts, can be sufficient through a small burr hole and fenestration of the cyst through a rigid neuroendoscope, with minimal risk of complications and good results on size of the cyst (71).
