WHO, World Health Organization; LITT, laser interstitial thermal therapy. There was no significant difference between age, gender, tumor etiology, tumor volume, radiation treatment, prior surgery, and time between surgery and post-operative scan. Two tailed Student’s t-test assuming unequal variances for continuous variables. Two-tailed Fisher’s exact test for categorical variables.
