Intracranial neurenteric cyst arising at the suprasellar cistern with extension to middle cranial fossa

摘要

IntroductionIntracranial neurenteric cysts are rare and are not often found in the supratentorial space. We present a case of an intracranial neurenteric cyst that arose at the suprasellar cistern with extension to the middle cranial fossa.HistoryA 3-year-old girl presented with seizure. Neuroimaging showed a huge extra-axial cyst involving the suprasellar cistern and left middle cranial fossa. Under the impression of an arachnoid cyst, she underwent fenestration of the cyst with basal cisterns and ventricle. The pathologic diagnosis was neurenteric cyst. Four years after the surgery, MRI showed no recurrence but did show poorly developed myelination of the left temporal white matter. Three years after surgery, seizures recurred. We consider epilepsy surgery in case of uncontrolled seizure.DiscussionWe discuss the unique case of supratentorially located neurenteric cyst that is just treated by fenestration. A close follow-up is needed for children with intracranial neurenteric cysts to surveil not only recurrence of lesion but also normal brain development.
