Unlike most previously reported neurenteric cysts, the MRI signal characteristics of this mass were such that it could not be determined if it is cystic or solid, being iso-intense on T1- and hyperintense T2-weighted images. Resection was performed through a median corporectomy of C6 and C7,...

They commonly occur in the middle or lower thoracic spine, less commonly in the lumbar region and lie posteriorly or posterolaterally in the spinal canal. Extradural arachnoid cysts pose a serious challenge to the...
