cystic dysraphic lesions

Cystic dysraphic lesions of the cervical and upper thoracic region are rare.

Cystic dysraphic lesions can be divided into categories that include both myelocystoceles and the so-called cervical meningoceles or myelomeningoceles.

Cystic dysraphisms of the cervical and upper thoracic region differ clinically and structurally from meningomyelocele and have a more favorable outcome.
