Presentation
Scoliosis
Patient Data
Dorso-lumbar kypho-scoliotic deformity convex to the right side.
Non-fused posterior neural arch of the lower dorsal and lumbosacral vertebrae. No evidence of overlying skin defects.
Capacious dorsolumbar spinal canal is noted.
An extramedullary intradural cyst is noted at L4 vertebral level showing calcific foci.
The spinal cord is seen split opposite the level of upper dorsal level down to the level of D12/L1 level. No evidence of osseous or fibrous septum is seen.
Extra lumbar vertebra is noted.
The spinal cord is seen split opposite the level of upper dorsal level down to the level of D12/L1 level. No evidence of osseous or fibrous septum is seen.
Syrinx is noted at D8 and D9 vertebrae and smaller one opposite to D11 vertebra.
Non-fused posterior neural arch of the lower dorsal and lumbosacral vertebrae. No evidence of overlying skin defects.
Capacious dorsolumbar spinal canal is noted.
An extramedullary intradural cyst is noted at L4 vertebral level.
Case Discussion
This a typical case of dorsolumbar kypho-scoliotic deformity with spinal cord diastematomyelia type II.
In cases of diastematomyelia, you should look for associated vertebral anomalies, in this case, there is an extra lumbar vertebra.
CT scan is done in these cases for better detection of segmentation anomalies and to assess if there is a bony septum between two hemicords. In this case, there is no bony or fibrous septum so it is considered to be type II.
