[edit] Discussion of Ventriculus terminalis

  • The ventriculus terminalis is a small, ependyma-lined, oval, cystic structure positioned at the transition from the tip of the conus medullaris to the origin of the filum terminale.
  • The ventriculus terminalis develops during embryogenesis as a result of canalization and retrogressive differentiation of the caudal end of the developing spinal cord and regresses in size during the first weeks after birth.
  • This variant causes no clinical symptoms.

[edit] Imaging Findings for Ventriculus terminalis
