Another congenital brain defect, encephalocele, is a protrusion of part of the brain through a defect in the skull.
The most common site for encephalocele is along the front-to-back midline of the skull, usually at the rear, although frontal encephaloceles are more common among Asians.
Defects in skull closure are thought to cause some cases of encephalocele, while defects in neural tube closure may cause others.
Surgery for encephalocele is possible only if there is a minimal amount of brain tissue protruding.
Surgical treatment of meningomyelocele and encephalocele may be successful, with lasting neurological deficiencies that vary in severity.
