Abstract: Objective To analyze MRI features of neurogenic bladder caused by tethered spinal cord. Methods MRI manifestations of 22 patients with neurogenic bladder due to tethered spinal cord were retrospectively analyzed.Results & Conclusion MRI can display the position of the spinal cord and the cause of tethered cord syndrome. Spinal deformations can also be displaied clearly. The characteristic signs of neurogenic bladder due to tethered spinal cord were the lower position of medullary cone (below L₁～L₂) and localized thickening or protrusion of the bladder wall.

Key words: tethered spinal cord, neurogenic bladder, magnetic resonance imaging
