My son is 21months old, he is still having problem to walk. We took advice from Pediatric, orthographic and Nero physician and surgeons. But nothing helped. MRI of cervicodorsal spine says Spinal cord shows vertical split in the lower dorsal region - overlying the D8 to L2 vertebral levels. The hemicords are asymmetric with larger left hemicord No bony septum could be delineated in available images. Please advise.
