Summary
Split cord malformation (SCM) Type II with dorsal lipomas is a rare condition. This case report details a 6-year-old girl with spastic paraparesis and a unique presentation of SCM Type II and twin dorsal lipomas.
Area of Science:
- Neuroscience
- Developmental Biology
- Pediatric Neurology
Background:
- Split cord malformation (SCM) encompasses various congenital anomalies of the spinal cord.
- SCM Type II is characterized by a bony or cartilaginous septum dividing the cord.
- The co-occurrence of SCM Type II and dorsal lipomas has not been previously documented.
Observation:
- A 6-year-old girl presented with a year of progressive spastic paraparesis and a lower back lipomatous mass.
- Radiological imaging confirmed Split Cord Malformation Type II with an associated dorsal lipoma.
- Intraoperative findings revealed a distinct dorsal lipoma associated with each hemicord.
Findings:
- Surgical excision of the twin dorsal lipomas was performed.
- The septum responsible for the cord split was transected.
- The proposed etiology involves premature separation of cutaneous and neural ectoderm during development.
Implications:
- This case expands the known spectrum of Split Cord Malformation presentations.
- Understanding the embryological basis may explain the occurrence of twin dorsal lipomas.
- Highlights the importance of thorough radiological and surgical evaluation for complex spinal anomalies.
