Intravenous contrast-enhanced (a) and non-enhanced (b) transverse CT projections. The images are oriented with dorsal at the top and the animal’s right to the left of the image. Both sections are at the level of L3–L4, and show irregularity and inhomogeneity of the iliopsoas muscles, with severe osteolysis of the vertebral body of the lumbar vertebra (L3) involving the spinal canal (black arrow). There is also discontinuity of the soft tissue of both the flanks indicating bilateral subcutaneous fistulae (white arrows)
