Figure 1. CST pathways affected or not affected by focal white matter lesions.

Figure 1

Pyramidal tracts (CST) in a 35-year-old male patient with clinically isolated syndrome (CIS) diagnosed two months ago (EDSS = 1) are shown. In the right hemisphere, CST is affected by a white matter lesion (the T2-intense lesion is shown in red, the T1-intense overlapping lesion is demonstrated in white). CST proportions passing the lesion are demonstrated in blue (affected CST, aCST). Within the left hemisphere CST (in blue) is not affected by any white matter lesions (not affected CST, naCST).
