Objective To study the MRI manifestations of tethered cord syndrome. Methods The MRI data were retrospectively analyzed in 14 cases of tethered cord syndrome. Results All these 14 cases were diagnosed by MRI. The physiological curvature of lumbar spine was normal in 7 cases, shallow in 3 cases and significantly enhanced in 4 cases. Spinal cord descended in all patients. Filum terminale diameter was normal in 1 case, and enlarged in the other 13 eases. The abnormal signals of short T1 and long T2 were seen in filum terminale in 12 cases and normal signals were seen in 2 cases. In 14 cases, 2 were complicated with spinal bifida, 1 double spinal cord, 2 syringomyelia, 2 sacral canal cyst, 1 enlargement of median cancal and 1 sacral crack. Meningoeele was found in 2 cases and lipomyelomeningocele was found in 12 cases. Conclusions MRI has a great value to the diagnosis and surgical treatment of tethered cord syndrome.
