Spinal segmental dysgenesis

Spinal segmental dysgenesis is a rare congenital spinal abnormality seen in neonates and infants, in which a segment of the spine and spinal cord fails to develop normally. The condition is segmental in nature, with vertebrae above and below the malformation. It is commonly associated with various abnormalities that affect the heart and genitourinary and gastrointestinal tracts and skeletal systems. We report two cases of spinal segmental dysgenesis with associated abnormalities.
