Figure 1: CT imaging centered on C7-T1 in the same horse. a) Coronal view showing endplate lysis (white arrow) and ventrolateral spinal cord compression. Moderate irregular periosteal proliferation is along the right lateral and ventrolateral aspect of C7 vertebral body. b) Sagittal view showing endplate lysis of caudal C7 (white arrowheads) and cranial T1 (black arrowhead). The dashed circle is focused on dorsal protrusion of soft tissue into the ventral spinal canal and dorsal extradural spinal compression resulting in overall reduced dural diameter. The intervertebral disc spacing is markedly narrowed. c) Axial view showing endplate lysis of caudal C7 (dashed white arrows) and cranial T1 (black arrows).
