1. Myelograph showing (a) narrowing and dorsal deviation of both the dorsal and ventral columns of contrast material at the level of T11-T12.
Myelograph showing (a) narrowing and dorsal deviation of both the dorsal and ventral columns of contrast material at the level of T11-T12. This lamb had vertebral body osteomyelitis resulting in erosion of vertebral bodies of T11 and T12. (b) Pooling of contrast material at the injection site (the lumbosacral junction). This myelograph has been taken too soon after administration of the contrast material as the dorsal contrast column is well established only as far as L3. The lesion in this case was at T10
