MRI Features of Spinal Enterogenous Cyst / 实用放射学杂志

ABSTRACT

Objective To explore MRI features of spinal canal enterogenous cysts.Methods The MRI features and differential diagnosis of 5 patients with spinal canal enterogenous cysts proved by surgery and pathology were reviewed retrospectively in combination with literature review.Results Of 5 cases,the cysts localized at cervical spine in 2,lumbar spine in 1,lumbosacral spine in 1 and the end of coccyx between rectum and cuticulum in 1.4 cysts were located at subdura,including anterior to the spinal cord in 3 and posterior to the spinal cord in 1.1 cyst located the end of coccyx between rectum and cuticulum was uncommunicated with spinal canal and 1 case associated with diastematomyelia.The spinal cords were compressed and displaced.The cysts were iso or slightly hyperintensity compared to CSF on T1WI,and similar intensity to CSF on T2WI.The cysts had no markedly enhancement on contrast-enhanced MR scan.Conclusion MRI has important value in diagnosing spinal enterogenous cysts.
