Cerebellar glioblastoma in childhood.

Cerebellar glioblastoma multiforme in childhood is extremely rare. Only ten such cases have been reported to date. Although treatment results are reported to be extremely poor, complete tumor clearance was achieved in a patient treated with superfractionated radiotherapy. She received high dose postoperative radiotherapy using a three times per day technique and is disease-free for more than three years posttherapy. This suggests that improved tumor response can be obtained by high dose postoperative radiotherapy using a modified fractionation technique.
