Figure 5.

Graphical representation of the contrast in intensity of left ION (A) and right ION (B) and the surrounding brainstem against days after surgery. The Bold red lines represent cases with POPCMS and the dotted blue lines represent cases without POPCMS. Graph of the average gradient of contrast in the left ION (C) and right ION (D) show clear difference in average gradient between POPCMS and non-POPCMS groups in the left ION (C) compared to the right (D). ION, inferior olivary nucleus; POPCMS, postoperative pediatric cerebellar mutism.
