Case 2 Post hoc manually aligned preoperative axial T2-weighted imaging with (A) iUS-1, (B) iUS-2, (C) iUS-3 with multiple tracts around and inside the tumor, and (D) iMRI axial T2-FLAIR imaging manually aligned with iUS-3 without the overlaid tracts. Notice on C the presence of tracts running through the tumor. On D, it is possible to notice the presence of residual tumor in the posterolateral margin as well as posteriorly along the medial margin in the vicinity of the coursing tracts through the tumor.
