Area of Science:

  • Neuroscience
  • Developmental Biology
  • Pediatric Surgery

Background:

  • Meningomyelocele is a complex neural tube defect.
  • High cervical meningomyelocele is rare and presents unique challenges.
  • Understanding atypical anatomical variations is crucial for surgical planning.

Observation:

  • A neonate exhibited a massive, fluid-filled high cervical meningomyelocele sac.
  • Magnetic resonance imaging showed a linear structure within the sac.
  • The spinal cord was otherwise normally positioned within the spinal canal.

Findings:

  • Intraoperative identification of a spinal cord-like structure within the meningomyelocele sac.
  • This structure, composed of glial tissue with an ependymal-lined cavity, connected to the sac's neural lining.

  • Fibrous strands tethered the structure, resembling ship rigging, extending superiorly into the spinal canal.

    • Implications:

    • This case highlights unusual morphological variations in meningomyelocele.
    • Histological confirmation of neural tissue within the sac and the spinal cord-like structure is significant.
    • Surgical excision provided a complete specimen for detailed analysis of these rare congenital anomalies.
