Giant meningoencephalocele with Arnold-Chiari type III malformation and anaesthetic challenges: A rare case report.

Meningoencephalocele means protrusion or herniation of brain (neural) tissue along with meninges through a defect in the cranium into a swelling filled with cerebrospinal fluid (CSF). It is very rarely associated with Arnold-Chiari type III (ACM type III). Size, location and type of content of the swelling determine the surgical as well as anaesthetic problems.
