Enterogenous cyst of the fourth ventricle

Abstract

✓ A case of a benign cyst within the fourth ventricle is described. The histology of the cyst wall lining resembled that of an enterogenous cyst of the spinal cord. The relationship between this cyst, colloid cysts of the third ventricle, and enterogenous cysts of the spinal cord is discussed.

Lateral extradural, supratentorial neurenteric cyst

“…Intracranial neurenteric cyst is very rare; the posterior fossa being the most favored location. [1][2][3][4][5] Although a few patients with supratentorial neurenteric cysts have been reported; 6,7 a laterally based supratentorial neurenteric cyst is exceptionally uncommon. [8][9][10] The rarity of supratentorial neurenteric cysts and their variable imaging features preclude preoperative diagnosis.…”

Rare Cervical Spine Neuroenteric Idem Cyst With Intramedullary Extension

“…[15] Neurenteric cysts were also reported intracranially. [16,17] and craniospinal cyst were also reported. [18] The embryological basis for the formation of neurenteric cyst was reviewed by several authors.…”

Staged bilateral far-lateral approach for bilateral cervicomedullary junction neurenteric cysts in a 10-year-old girl

“…However, mucoid or xanthochromic cyst contents have also been described in the literature. [1][2][3]11,13,26,31 Histologically, the neurenteric cyst wall is typically lined by simple or pseudostratified cuboidal or columnar epithelium with a basement membrane resembling either gastrointestinal-like or respiratory-like epithelium. 18 Of the neurenteric cysts described in the literature, about 50% are lined with gastrointestinal epithelium, and 17% with ciliated respiratory epithelium, while the remaining cysts share mixed characteristics of the above types and also may contain pancreatic or squamous epithelium.…”

“…2,3,6 Although these lesions may occur anywhere in the central nervous system and represent 0.01% of all central nervous system tumors, they are most commonly located in the spine, particularly in the lower cervical and upper thoracic regions, and make up 0.3%-0.5% of all spinal tumors. [1][2][3]7,8 Intracranial neurenteric cysts are exceptionally rare and represent only about 10%-17.9% of all neurenteric cysts. 31 According to a recent (2012) review by Gauden et al, 13 only 140 patients with intracranial neurenteric cysts have been reported in the literature since 1952.…”
