Spinal neurenteric cysts

Spinal neurenteric cysts are a rare type of foregut duplication cyst, accounting for ~1% of all spinal cord tumors. They are usually classified as spinal or intracranial and are associated with vertebral or CNS abnormalities respectively. 

Neurenteric cysts result from incomplete resorption of the neurenteric canal. The intraspinal cysts are usually intradural extramedullary (80-90%) 4 and ventral in location. They most commonly occur in the thoracic region (~40%).

The cyst is seen as a hypoattenuating lesion which may show soft tissue attenuation.

It is the investigation of choice and the appearance depends on the variable protein content:

  • T1: variable signal intensity
  • T2: variable signal intensity

These lesions can recur and hence MRI is also used for follow up.
