Summary
This study suggests lumbar split cord malformation (SCM) and Klippel-Feil syndrome (KFS) are linked, not coincidental. Klippel-Feil syndrome may represent a mild form of occult spinal dysraphism.
Area of Science:
- Neurology
- Developmental Biology
- Orthopedics
Background:
- Klippel-Feil syndrome (KFS) is a congenital disorder characterized by the fusion of cervical vertebrae.
- Split cord malformation (SCM) is a rare congenital anomaly of the spine.
Observation:
- A case report details a patient with both type II split cord malformation (SCM) and Klippel-Feil syndrome (KFS).
- Review of existing literature was conducted alongside the case presentation.
Findings:
- The co-occurrence of lumbar SCM and KFS in the same patient is proposed to be embryologically related, not coincidental.
- Klippel-Feil syndrome, in some presentations, may be a forme fruste (mild, incomplete form) of occult spinal dysraphism.
Implications:
- This finding suggests a potential shared developmental pathway between KFS and SCM.
- Reclassifying certain KFS phenotypes as related to spinal dysraphism could impact diagnostic and treatment approaches.
- Further research into the embryological link between these conditions is warranted.
