Radiology Cases Spinal Dysraphism LSBU

Description: Failure of spinal or neural tube fusion
The first feature to appear on the embryological plate is the neural groove that deepens with in-folding of its edges to form the neural tube. The openings of the tube close at 26-28 days after conception. Failure of closure at the top end causes anencephaly and at the lower end, a meningomyelocoele with pilonidal sinus. The lumen of the tube forms the central canal of the spinal cord and expands, with budding of the cephalic end of the nervous system, to make the ventricular system in the brain. The tissues, bordering the neural tube, are induced to make supporting structures and neural tube abnormalities will influence mesenchymal evolution to normal axial skeleton.
The classification includes:
* abnormalities of vertebral arch fusion, Cleft of vertebra or hemi-vertebra.
* Spinal dysraphism
* Diastematomyelia
