Schmidt, Meic H. | Spinal extradural arachnoid cysts: clinical, radiological, and surgical features | Extradural arachnoid cysts in the spine are rare and are seldom a cause of spinal cord compression. They are thought to arise from congenital defects in the dura mater, and they almost always communicate with the intrathecal subarachnoid space through a small defect in the dura.
