[edit] Discussion of Lateral meningocele

  • A lateral meningocele is a cerebrospinal fluid–filled protrusion of dura mater and arachnoid that extends laterally through an enlarged intervertebral foramen into the paraspinal, intrathoracic, or retroperitoneal region.
  • Lateral meningoceles occur unilaterally or bilaterally and as solitary or multiple lesions.
  • Lateral meningoceles mainly occur in the thoracic or lumbar spine.
  • Patients may be asymptomatic or have slight sensory or motor deficiencies and sometimes develop severe scoliosis.
  • Lateral meningocele may be associated with mesenchymal disorders such as Marfan, Ehlers-Danlos syndrome or neurofibromatosis.

[edit] Imaging Findings for Lateral meningocele

  • Spinal US shows a cystic mass in an expanded spinal canal.
  • The adjacent spinal cord is displaced and may be compressed by the meningocele.
  • Secondary bone abnormalities such as erosion of vertebral bodies, thinning of vertebral arches, and enlarged intervertebral foramina due to mass effect can be demonstrated with spinal radiography, computed tomography, or magnetic resonance imaging.
