80 y/o man with a history of a bladder cancer, now presenting with lower back pain.

Image Findings

Splitting of the dural sac is noted at the L4-5 level. Possible splitting of the filum terminale is seen as well. Plain films (not shown) showed no skeletal abnormalities except for some degenerative changes.


Diastematomyelia is characterized by spitting of the spinal cord or filum terminale. About 50% of the cases occur in the lumbar region. Associated bony and skin abnormalities are common, including an osseous spur in about 1/2 the cases.
