Second Surgery in Insular Low-Grade Gliomas

Figure 3

(a) Showing a TR 62 months after the first surgery. The patient did not receive any adjuvant therapy since the first surgery. The volumetric data at first surgery are shown in Figure 2. At second surgery the preoperative tumor volume computed on T2-weighted MRI was 37 cm³. Volumetric analysis of postoperative tumor residue computed on T2-weighted MRI showed a tumor residual volume of 4 cm³ (axial slices), which has grown mainly in the previous cavity (b). The extent of the tumor volume resection, computed on a T2-weighted MRI sequences, was 91%.
