AB Key  PointsHemivertebrae  are  a  major  cause  of  congenital  scoliosis  and  kyphoscoliosis.Incidence  is  0.3  to  1  per  1000  livebirths.  More  common  in  females.Vertebral  anomalies  develop  during  first  6  weeks  of  gestation.Hemivertebrae  act  as  a  wedge  within  the  vertebral  column,  causing  curvature  away  from  side  of  defect.Prognosis  for  isolated  hemivertebra(e)  is  good.Can  be  associated  with  neural  tube  defects,  occult  intraspinal  defects,  renal  anomalies,  tracheoesophageal  atresia/fistula.Associated  syndromes  in  the  differential  diagnosis  include:  Goldenhar,  Jarcho–Levin,  Poland,  Robinow,  chondrodysplasia  punctat,  Alagille,  and  Pallister–Hall.
