Epidural Arachnoid Cyst
Evidence of an oblong posterior epidural lesion posteriorly extending from D11-L2 levels appearing hypointense on T1 weighted images and hyperintense on T2 WI, with no significant enhancement & scalloping of the posterior elements at these levels. Possible posterior epidural arachnoid cyst. This is a 14 year old boy with back pain.
Learning Point: Epidural cysts are most commonly located posteriorly and displace the dura. Larger lesions may cause symptoms by compressing the spinal cord. Most occur in the thoracic spine posteriorly. There may be erosion of the adjacent bony elements of the spinal canal.
