Spinal neurenteric cyst
Updates to Article Attributes
Neurenteric cysts isare a rare type of foregut duplication cyst, associated either with vertebral or central nervous system abnormalitiesaccounting for ~1% of all spinal cord tumours. They are usually classified as spinal or intra-cranialintracranial, and are associated with vertebral or CNS abnormalities respectively.
Pathology
TheNeurenteric cysts result from incomplete resorption of neurenteric canal. The intraspinal cysts are usually intradural extramedullary (80-90%)4 and ventral in location. They most commonly occur in the thoracic region (42(~40%).
Pathology
They result from incomplete resorption of neurenteric canal.
Radiographic features
CT
The cyst is seen as hypoattenuating lesion which may show soft tissue attenuation.
MRI
It is the investigation of choice and the appearance depends on the variable protein content.:
- T1: variable signal intensity
- T2: variable signal intensity
Treatment and prognosis
These lesions can recur and hence MRI is also used for follow up.
