Microsurgery Resection of Intrinsic Insular Tumors via Transsylvian Surgical Approach in 12 Cases

Figure 1-15 MR DTI (Figure 1-5) can assess the completeness and consistency of the white matter fibers, “depression, edema, infliction, and damage” by the tumor. The pyramidal tracts and the deep white matter were partially invaded and damaged. MRI (Figure 6-15), preoperative axial (Figure 7, 9), sagittal (Figure 6, 8), and coronal (Figure 10) T1-weighted enhancecd image showed tumor were hyper-signal with sharp border. Marked edemas surrounded the location at the medial temporal base and the insular lobe. Postoperative axial T1-weighted image (Figure 11, 12), T2-weighted image (Figure 13, 15) and T2 flair image (Figure 14) showed total tumor removal with mild edema surrounding.
