Fig. 1

A 65-year old man showing multiple enhancing lesions involving the right frontal lobe, corpus callosum body/splenium, and right parietal lobe on (a) preoperative magnetic resonance imaging. The patient was pathologically confirmed as IDH1 wild-type glioblastoma with methylated MGMT promoter after receiving partial resection of the tumor followed by temozolomide-based chemoradiotherapy of 60 Gy in 30 fractions. b Using 2 partial arcs, the maximum dose to the right (ipsilateral, blue contour) and left (contralateral, green line) hippocampi were 16.93 Gy and 16.38 Gy, respectively, on a volumetric-modulated radiotherapy plan. Abbreviations: IDH1, Isocitrate dehydrogenase 1; MGMT, O6-methylguanine-DNA methyltransferase
