Summary
Neurenteric cysts are rare congenital spinal canal lesions originating from embryonic germ cell layer malformations. These unusual craniocervical cases in children highlight complex surgical challenges and associated bony anomalies.
Area of Science:
- Neuroscience
- Developmental Biology
- Pediatric Neurosurgery
Background:
- Neurenteric cysts are rare central nervous system lesions of intestinal epithelial origin.
- They arise from abnormal germ cell layer separation during embryonic development, persisting as entodermal elements in the spinal canal.
- Commonly found in the cervical region, ventral to the spinal cord, they are identified by markers like vertebral anomalies and keratin.
Observation:
- This study details three unusual cases of childhood craniocervical intradural neurenteric cysts in patients aged 4-8 years.
- Cysts were located ventrally from the craniocervical junction to C6, associated with bony anomalies (bifid clivus, hemivertebrae, blocked vertebrae).
- Clinical presentations included cervical cord compression and recurrent meningitis, with complex surgical interventions required.
Findings:
- Pathological diagnosis confirmed neurenteric cysts lined by nonciliated, mucin-producing cuboidal or columnar epithelium.
- Surgical management varied, involving laminectomies, myelotomy, vertebrectomy, and anterior excision with fusion, complicated by bony and vascular anomalies.
Implications:
- Neurenteric cysts are uncommon congenital anomalies that can manifest symptomatically in pediatric patients.
- These cases underscore the diagnostic and surgical complexities of craniocervical neurenteric cysts in children.
- Early recognition and tailored surgical approaches are crucial for managing these rare pediatric CNS lesions.
