Neurenteric cysts are rare congenital benign lesions of the central nervous system. These are essentially congenital endodermal cysts. Neurenteric cysts are seen more frequently in the spine than the brain (3:1), in particular involving the lower cervical/upper thoracic spine. Neurenteric cysts represent 0.31.3% of all intra spinal cystic lesions and are extremely rare intra cranially [1]. In t...

The congenital malformation known as an intraspinal bronchiogenic cyst is a rare form of endodermal (neurenteric, enterogenous) cyst lined with respiratory tract epithelium. We describe 3 new cases of intradural extramedullary bronchiogenic cyst in the Department of Neurosurgery between the years 2006 and 2014. Three patients were performed resection of intradural extramedullary bronchiogenic c...

A variety of cystic lesions may develop in spinal canal. These cysts can be divided into intramedullary, intradural, extradural, cervical, thoracic, lumbar, and sacral cysts according to anatomical presentation, as well as arachnoid, meningeal, perineural, juxtafacet, discal, neurenteric cysts, and cyst-like lesions according to different etiologies. Mechanisms of initiation and growth vary for...

A 28-year-old woman presented with left-sided frontotemporal headache lasting 6 wk. Head CT and MR imaging revealed a clival mass, which was interpreted as a chondrosarcoma. The lesion was removed at endoscopic endonasal surgery; histologic and immunohistochemical findings proved it to be neurenteric cyst. On CT scans, the lesion was lytic, with an intact cortex; it was uniformly hyperintense r...

Neurenteric cysts (NC) are rare, endodermal-derived intracranial lesions, commonly located anteriorly in the posterior cranial fossa. We describe a rare case of a giant posterior fossa NC (6.5 × 5.9 × 4.3cm) located dorsal to the brain stem in a Chinese woman with a 1 week history of cerebellar symptoms. To our knowledge, this is the largest documented cyst of this type and the third dorsally l...

We report serial MR findings in a middle-aged woman with a neurenteric cyst involving the cerebellopontine angle cistern with xanthogranulomatous changes. On the initial gadolinium-enhanced T1-weighted MR images, the solid portion of the lesion had homogeneously strong enhancement. Follow-up MR images obtained 6 months later showed that the mass had increased in size; however, the solid portion...
