Postoperatively, slight contrast-enhancement appeared on the right side of pons on MRI (arrow). Therefore, we started HD-MTX therapy (3.5 g/m2) at 3 months after operation. The contrast-enhancement on the right side of pons almost disappeared after 5 courses of HD-MTX

MRI showed the new contrast-enhancement in the dorsal pons accompanied by expansion of high intensity area on FLAIR images only 1 month after completion of 5 courses of HD-MTX therapy (arrow). The patient was re-treated with 3 courses of HD-MTX (4.5 g/m2) followed by whole brain irradiation (30 Gy). After irradiation, not only contrast-enhancement but also FLAIR-high intensity areas almost disappeared
