Summary
The unified theory explains split cord malformations (SCMs) originating from a neurenteric canal error during development. Three pediatric cases provide evidence supporting this embryogenetic model for SCMs.
Area of Science:
- Developmental Biology
- Neuroscience
- Pediatric Surgery
Background:
- Split cord malformations (SCMs) are complex congenital vertebral anomalies.
- Previous theories on SCM embryogenesis lacked a unified explanation for all variants.
Observation:
- Pang et al.'s unified theory posits a single embryogenetic error involving an accessory neurenteric canal.
- This error leads to an endomesenchymal tract that splits the notochord and neural plate.
- Three pediatric cases with SCMs were analyzed to evaluate the unified theory.
Findings:
- Case 1: A 3-month-old girl presented with combined SCM types at T11.
- Case 2: A 2-week-old girl had type-II SCM with associated spinal dysraphic abnormalities.
- Case 3: A 3-month-old boy with type-II SCM exhibited a lipomatous tract with lymphoid and epithelial tissues.
Implications:
- The presented cases lend support to the unified theory of SCM development.
- This theory offers a cohesive framework for understanding the embryogenesis of diverse SCM presentations.
- Further research validating this model could refine diagnostic and therapeutic strategies for SCMs.
