These classification of cysts are embedded in the endoderm (inner layer) and the ectoderm (outer layer) of the cranial or spinal cord germ layers.They normally take over the neuraxis, the axis of the central nervous system that determines how the nervous system is placed, which allows the cysts to infiltrate the CNS tissues.

The resulting cyst can then block the normal flow of CSF from the brain resulting in hydrocephalus as well as other defects.
