According to Hingwala  and Periakaruppan  et al, a large peak was found at 2.0 ppm is found in the place of NAA in neurenteric
cysts which was not present in other benign or developmental cysts.
cysts are usually found in the posterior mediastinum, these lesions are typically classified with other foregut cysts and will be briefly covered here.

cyst in an adolescent patient," Journal of Korean Neurosurgical Society, vol.
canal cyst is presumably the result of incomplete separation of the notochord from the foregut in embryogenesis.
Differentiation from other cystic lesions of the mediastinum like neurenteric
cyst, pericardial cyst, thymic cyst, bronchogenic cysts, meningocele, lymphangioma, mature cystic teratoma, cystic schwannomas, cystic thymomas, and cystic tubercular lymphadenitis is important as it has important implications in further management of the patient.
(3,7) However, when a neurenteric
lesion is suspected an MRI would be helpful to detect vertebral and intraspinal anomalies and, therefore, would be the diagnostic investigation of choice.
During this phase, there is a transient communication between the amnion and yolk sac, called the neurenteric
When the location is atypical, such as an infratentorial location as in our case, cystic lesions of the involved region, for example, neurenteric
cysts for posterior fossa lesions, are first considered in the differential diagnosis.
Others include the split notochord theory which explains the formation of neurenteric
duplications and associated vertebral anomalies.
Patients with neurenteric
cysts may present with clinical symptoms such as headache, dizziness, cranial nerve deficits (decreased sensation in 5th nerve territory, sensorineural hearing loss, or 3rd nerve palsy), focal neurologic deficits, or seizures [32, 34].
