AbstractNeurenteric cysts are rare congenital, benign, endodermal lesions of the central nervous system that occur mainly in the spinal canal. Intracranial neurenteric cysts are rare; the posterior fossa being the most common site. A laterally based supratentorial neurenteric cyst is exceptionally uncommon. The rarity of supratentorial neurenteric cysts and their variable imaging features preclude preoperative diagnosis. A search of the literature revealed no other extradural supratentorial neurenteric cyst. We present a patient with an extradural giant neurenteric cyst that occupied both the supratentorial and infratentorial compartments, further highlighting the heterogeneity of this rare intracranial lesion and emphasizing the need to consider this in the differential diagnosis of cystic intracranial brain lesions.
