Retrospective analysis of intraspinal enterogenous cyst / 第三军医大学学报

ABSTRACT

Objective To improve the diagnosis and treatment of neurenteric cyst. Methods The clinical manifestations, MRI characteristics and surgical results of 11 cases of intraspinal neurenteric cysts were analyzed. Results Positive pathological signs and paresis appeared in all cases, and radicular pain in 9 cases. The symptoms were episodic in 2 cases whose courses were more than 3 years. MRI could clearly demonstrate the exact extension of the cyst and the surrounding structures. These cysts showed as slightly long T 1, long T 2 homogeneous signal on MRI. Their neurological functions improved steadily after complete resection in 8 cases, subtotal resection in 3 cases. Conclusion Neurenteric cysts are rare congenital lesions, often associated with vertebral anomalies and occurred at subdural cervical location, anterior to the cord. MRI is a more effective and convenient method for neurenteric cyst image investigation. Total or subtotal resection of neurenteric cysts with subsequent recovery in neurological function is usually possible.
