cysts are rare, benign, congenital endodermal lesions, more commonly located in the spine than in the brain (posterior fossa).
Mediastinal foregut duplication cysts are further classified into bronchogenic, esophageal and neurenteric
Radiologic impression indicated a benign tumour, such as a neurogenic tumour with cystic change or a neurenteric
cysts (SNCs) are relatively rare congenital lesions.
The diagnosis of intrathoracic cysts is challenging because of several possible pathologic findings, including bronchogenic cysts, neurenteric
cysts, and other foregut duplication cysts.
This explains neurenteric
cysts, which are proposed to be impaired separation of the notochord from intestinal endoderm and formation of neurenteric
bands that, with embryonal growth, produce traction diverticula.
Among them, epidural lipomatosis usually occurs in obese people, patients with a history of corticosteroid use, and those with an endocrinopathy. The Kovalevsky or neurenteric
canal is defined as a canal connecting the neural tube and archenteron in the embryo, resulting from a persisting abnormal communication between the notochord and yolk sac and the amnion during an early stage of embryonic development.
They include pericardial and neural cysts, bronchogenic cysts, esophageal duplication cysts, neurenteric
cysts, and cysts of other origin.
Enteric cysts associated with vertebral anomalies are called neurenteric

cyst, the Rathke cleft cyst and the colloid cyst constitute a same entity?" Acta Neurochirurgica, vol.
Much rarer primary tumors are schwannomas of other cranial nerves: of the trigeminal nerve, of the facial nerve, or of the caudal cranial nerves; paragangliomas, chordomas, chordosarcomas, arachnoid or neurenteric
cysts, dermoid tumors, and metastases5.
