distal part.
Figure 2 - 2019, atrophy involved the left leg.
Figure 3 - 2015, T2-weighted MRI of thoracic spine, anteroposterior size
6.75 mm, width 7.74 mm, cavity size 1.87 mm (anteroposterior size and
width lines are offset to avoid overlapping).
Figure 4 - 2019, T2-weighted MRI of thoracic spine, anteroposterior size
6.53 mm, width 7.27 mm, cavity size 2.02 mm (anteroposterior size and
width lines are offset to avoid overlapping).
Figure 5 – 2019, T2-weighted MRI shows dilated central canal at the
C6-Th1 vertebrae level and slightly narrow of vertebral canal (vertebral
canal is less than vertebrae’s front-rear size). (Unfortunately the
patient was unable to provide previous MRI from 2014 and 2018)
