Objective: To study the MRI manifestations of intraspinal enterogenous cysts. Methods: The MRI findings and related clinical data of 20 cases with enterogenous cysts proved by surgery and pathology were collected and analyzed. Results: Nineteen lesions of 20 cases located in the subdural extramedullary space. Among which, 10 lesions occurred in the cervical segment, 4 lesions in the junction of cervical and thoracic segments and 5 lesions in the thoracic segments. One lesion occurred in the thoracic spinal cord. All the lesions with well-defined margin presented with uniformity long T1 and long T2 signal in plain MRI and had no enhancement on the postcontrast images. 15 lesions showed sign of spinal cord incuneation. 4 cases associated other abnormity of the spinal column. Conclusion: MRI can make the correct preoperative diagnosis according to the appearance, signal features and preferable location of enterogenous cysts.
