Endodermal cyst presenting as a prenatally diagnosed large intracranial cyst: Case report and review of the literature

Endodermal cysts of the central nervous system are unusual lesions. Most reported cysts develop in the spinal canal, whereas others, which occur intracranially, are usually located in the posterior fossa. Although endodermal cysts are considered congenital, a prenatal diagnosis has not been reported. In this report the authors present an extremely rare case of a large intracranial endodermal cyst detected prenatally and treated successfully after birth.
