Cervico-thoracic neurenteric cyst: clinicoradiological correlation with embryogenesis.

Two cases of cervico-dorsal neurenteric cysts are presented, one located dorsal and the other ventral to the spinal cord, with associated Klippel-Feil anomaly, meningocele, spinal dysraphism and possibly spinal cord malformation. One patient was operated on as a neonate for a cervico-thoracic meningocele and presented during adolescence with spastic quadriparesis. Imaging revealed spina bifida, a dorsally located neurenteric cyst and a tendency towards split cord malformation. The other child presented with cervico-thoracic kyphoscoliosis and paraparesis. Imaging demonstrated persistence of a cervico-thoracic remnant of the primitive neurenteric canal through the upper thoracic spine.
