Fig. 1. (A) Sagittal T1- and T2-weighted magnetic resonance imaging (MRI) scan showed syringomyelia in the thoracolumbar region. There is a marked increase in the size of the syrinx cavity, mainly at the L1-L3 level (small arrows). (B) There is a narrow vertebral canal and enlarged spinal cord diameter, as seen in the axial MRI scan. (C) Postoperative X-ray view showing thoracic placement of the epidural percutaneous leads at the T9 and T10 vertebral levels.
