title: Gas-filled intradural cyst of the lumbar spine. Case report.
abstract: The authors describe the case of a gas-filled intradural cyst of the lumbar spine that caused radicular pain. The cyst was similar to an intervertebral vacuum disc phenomenon and the cystic gas collection resembled the features of gas-containing pseudocyst, herniated intradiscal gas, or free gas, all of which have been found in the epidural space.
