AB It  is  a  rare  form  of  spinal  dysraphism  resulting  in  division  of  the  spinal  cord  into  two  parts  by  a  fibrocartilaginous  or  bony  posterior  projection  of  the  posterior  vertebral  body.  It  is  characterized  by  the  presence  of  a  complete  or  incomplete  sagittal  cleft  of  varying  extent  that  splits  the  spinal  cord  into  two  hemicords  at  the  conus  medullaris,  or  filum  terminale.  It  is  often  associated  with  splaying  of  the  posterior  vertebral  elements.  This  condition  is  caused  by  an  osseous,  cartilaginous,  or  fibrous  septum.  It  may  be  isolated  or  associated  with  other  segmental  anomalies  of  the  vertebral  bodies.  When  the  split  does  not  reunite  distally  to  the  spur,  the  condition  is  referred  to  as  a  diplomyelia  or  true  duplication  of  the  spinal  cord.  The  clinical  features  may  include  neurologic  deficits  of  the  lower  limbs  and  perineum,  causing  gait  disorders,  sphincter  disturbances,  muscular  atrophy,  reflex  changes,  congenital  scoliosis,  and  foot  deformities.
