Spectrum of Nonterminal Myelocystoceles

Abstract

The nonterminal myelocystocele is a distinct form of closed spinal dysraphism characterized by a skin-covered meningocele, which is either crossed by a fibroneurovascular stalk that extends from the dorsal aspect of the spinal cord to attach to the dome of the meningocele (abortive form, or myelocystocele manqué) or contains a hydromyelic cavity that is continuous with the ependymal canal of the spinal cord (complete form).
