Lateral thoracic meningocele

Lateral thoracic meningoceles are a type of spinal meningocele.


As with any meningocele, it results from herniation of the meninges through a foramen or a defect in the vertebral column. 


They are typically associated with neurofibromatosis type I but can rarely occur in isolation. In these patients, they may occur in association with thoracic spine scoliosis.  

When scoliosis/kyphosis is present, the meningocele is located at the apex of the convexity.

Radiographic features
