Lateral thoracic meningocoele

A lateral thoracic meningocoele is a type of spinal meningocoele.


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


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

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