Abstract
|
|
|
|
A 24-year-old woman presented with headache and subjective gait disturbance. Neurological examination was unremarkable. Brain magnetic resonance imaging demonstrated a posterior fossa cyst and hydrocephalus. Surgical removal of the cyst was done. The cyst had the unique histological feature of a single-layered cuboidal epithelial lining. Detailed immunohistochemical study supported a neuroectodermal origin. The differential diagnosis and the histogenesis of epithelial cysts in the central nervous system are discussed.
