Lipomyelomeningocele

Lipomyelomeningoceles are one of the forms of closed spinal dysraphism. They usually present as a subcutaneous fatty mass just above the intergluteal cleft. However, some lipomyelomeningoceles may occur at other locations along the spinal canal.

Lipomyelomeningoceles may be clinically detectable as a subcutaneous fatty mass above the intergluteal crease.

These lesions are formed mainly due to a defect in primary neurulation in which mesenchymal tissue enters into neural placode and forms lipomatous tissue.

MRI
  • typically seen as a spinal defect with lipomatous tissue, covered with skin
  • neural placode-lipoma interface lies outside the spinal canal due to enlargement of subarachnoid space
  • low-lying cord is usually present
  • lipomyelocele: placode-lipoma interface lies within the spinal canal
