Cervical Intradural Disc Herniation and Intradural Gas on CT Scan

Abstract

Intradural disc herniation has been reported as a rare type of intervertebral disc herniation, only 32 cases reported. It remains difficult to definitively diagnose the disease before surgery. We reported a 55 year-old female patient complaints of nuchal pain and bilateral arm weakness after a trauma accident. MRI revealed a C3-C4 herniated intervertebral disc (HIVD) with a ＂hawk-beak sign.＂ CT scan image revealing two small gas bubbles in the spinal canal at C3-C4 level. In previous study, the presence of epidural gas on CT scan might suggest the potential presence of an intradural disc herniation in the lumbar spine. To our knowledge, this is the first case of cervical intradural herniated disc with intradural gas on CT scan.
