Neurenteric canal cyst is presumably the result of incomplete separation of the notochord from the foregut in embryogenesis.
Moreover, in a child with atypical meningitis and large unexplained nontraumatic pneumocephalus, neurenteric fistula as a possible etiology needs to be strongly considered.
Spinal neurenteric cysts are infrequently reported congenital abnormalities that are believed to be derived from an abnormal connection between the primitive endoderm and ectoderm during the 3rd week of life.
