Spinal Dysraphism and Congenital Abnormalities

Spinal Dysraphisms… the “-celes”

• Lipocele

• Myelocele

• Myelomeningocele

• Lipomeningocele

• We need to address the neural placode

  • This is basically the neural tissue that is fucked up for whatever reason

  • If it remains in the spinal canal then there is no myelocele

  • If the tissue protrudes through the defect then there is a myelocele

• s

Lipomyelocele

• Basically within the spine communicates with the sub-Q tissues

• If there is associated protrusion of neural tissue (neural placode) into the defect then it is called lipomyelomeningocele

Caudal Regression

• Basically fucked up distal spine/sacrum/coccyx with associated spine and cord issues

• Associated with multiple other congenital fuck shit - especially bladder and renal issues

• Type 1

  • Conus is blunt and terminates high

  • Severe sacral malformations or absence

  • May have dilattaion of central canal of cord

  • May have cyst on conus

• Type 2

  • Conus terminates low with tethered and thick filum terminale

  • May have intraspinal lipoma

  • Neuro issues are more severe

  • Honestly looks similar to tethered cord

Fibrolipoma

• Basically fat and fibrous tissue at distal cord/filum

• No associated complications, purely incidental

• Conus terminates at normal level!

Diastematomyelia

• Basically duplicated cord
