 | Media file 21: Axial CT scans through the upper lumbar spine show a split cord. |
 | Media file 22: T1- and T2-weighted sagittal MRIs of the lumbar spine show an extradural spinal lipoma communicating with the subcutaneous fat. |
 | Media file 23: T1- and T2-weighted sagittal MRIs of the lumbar spine show an intradural sacral lipoma. Note the scalloping of the posterior sacral vertebral bodies and the syrinx. |
 | Media file 24: Axial CT scans through the lumbosacral junction shows absence of the posterior spinal elements at L5-S1. Note sclerosis of the laminae and the wide spinal canal. |
 | Media file 25: Plain radiographs show posterior scalloping. |
 | Media file 26: T2-weighted sagittal MRIs of the sacrum show an anterior sacral meningocele. |
