Segmental spinal dysgenesis

What it is

A rare complex congenital spinal anomaly characterized by localized agenesis/dysgenesis of the spine (usually lumbar or thoracolumbar spine), kypho-scoliotic deformity (including severe congenital kyphosis or kyphoscoliosis) and focal abnormalities of the underlying spinal cord and nerve roots. Typically, there is segmental absence or malformation of the spinal cord characterized by normal upper spinal cord and significantly abnormal (thinned or even barely perceptible) affected cord segment without nerve roots, and a thickened, bulky distal cord. Closed spinal dysraphism may be present. Majority of the affected individuals present with neurogenic bladder (sometimes with vesicoureteral reflux), severe motor impairment (spastic paraparesis/paraplegia), reduced or absent tendon reflexes and severely hypotrophied and deformed lower limbs. In some patients clonus, hypotonia, clubfoot, horseshoe kidney and bilateral hip dislocation were reported.

ICD-10 codes

ICD-10 has no distinct code for most rare diseases, so many are filed under the nearest available one. A shared code identifies the group, not this disease — the ORPHAcode above is what identifies it.

Reached through the ICD-10 categories this disease is filed under, so these describe the broader group rather than this disease specifically.
