*Spina bifida.
**Associated with: sudden death, sleep apnea, cerebellar ataxia.
**Spina bifida cystica.
*Chiari type II - often assoc. with hydrocephaly at birth.
***Meningocele - less severe, herniation of only the membrane.
*Chiari type III - cerebellum + brain stem herniate through foramen magnum +/- encephalocele.<ref>URL: [http://www.ninds.nih.gov/disorders/chiari/detail_chiari.htm http://www.ninds.nih.gov/disorders/chiari/detail_chiari.htm]. Accessed on: 6 May 2011.</ref>
