Vertebral and Spinal Cord MR

Findings: no evident abnormal change of the sacral curvature; stripy adipose signal in the medial posterior region of vertebral canal in the level of L5 and S4, part of the cauda equina was tethered to the upper canal, the spinal cord was rope-like, the conus medullaris was in low position; central canal dilation; discontinuity of the central vertebral lamina in the level of S2, exhibiting slit-like change, with visible subcutaneous atresia-like sinus tract in corresponding level.

Impression:

Spinal malformation: 1) spina bifida occulta of sacral vertebrae; 2) lipomyoma in sacral canal; 3) rope-like spinal cord with central canal dilation, tethered spinal cord.
