Mediastinal foregut duplication cysts are further classified into bronchogenic, esophageal and neurenteric cysts
Spinal 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.
In the posterior mediastinum two patients had bronchogenic cysts and duplication cyst, Neurenteric cysts
were found in one and three cases respectively.
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 cysts
. These are usually seen associated with vertebral anomalies like vertebral fusion, scoliosis, anterior and posterior spina bifida, hemivertebrae, diastomyelia, and absence of vertebra .
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.
. Neurenteric cysts
are rare, benign, congenital, endodermal lesions, more commonly located in the spine than in the brain.
are uncommonly reported congenital abnormalities that are thought to be an abnormal connection between the endoderm and ectoderm during the 3rd week of life.
in children: 16 consecutive cases and review of the literature.
