Anterior meningocele

Last revised by Tristan Skalina on 8 Oct 2023

Anterior meningocele is characterized by herniation of CSF-filled sac through an anterior osseous defect.

It usually occurs in the sacral region where it is termed an anterior sacral meningocele although it can also occur in other areas like the thorax 2

When present in the sacrum, it is often found in the caudal regression syndrome.

It is in continuity with the thecal sac and lined by arachnoid and dura mater, but does not contain neural tissue.

Contrary to the more common dorsal meningocele, it does not belong to the group of closed spinal dysraphism with a cutaneous mass.
