Meningoceles (also spelled meningocoele) are protrusions of the meninges through a defect or weak point in the skull or spine, usually involving the soft tissues beneath the surface of the skin. They are typically categorized into congenital, iatrogenic (e.g. following a craniotomy, sinus surgery, or as a laminectomy complication), and spontaneous. 

A differential diagnosis for both spinal and cranial acquired meningoceles are pseudomeningoceles, which are CSF collections not lined by dura.
