School ager with skin stigmata along the spine

CT of diastematomyelia
AP radiograph of the spine (left) suggests a linear piece of bone in the center of the spinal canal at the L2-L3 level. Axial CT without contrast of the spine at the L2-L3 level (right) shows the spinal cord and thecal sac are bisected by a boney bridge in the center of the spinal canal. There is also evidence of vertical fusion of the spinal lamina.

The diagnosis was diastematomyelia.
