Intracranial Neurenteric Cyst of the Anterior Brain Stem in a Girl

ABSTRACT

Neurenteric cyst is a rare, congenital, and benign cystic lesion of the central nervous system, which is generally thought to result from failure of separation of the neuro-ectodermal and neuro-endodermal elements during week 3 of embryogenesis. Neurenteric cysts in the intracranial area are very rare lesions that typically occur in the spinal canal or even more seldom in the posterior cranial fossa. A girl presented to the outpatient clinic with complaints of moderate to severe episodes of headache with associated vomiting for 2 weeks. There was a positive sign of severe neck stiffness. Her brain MRI showed a neurenteric cyst located within the anterior intradural space of the foramen magnum. We report our experience with an intracranial neurenteric cyst located in the anterior brain stem area.
