This study is a histological and clinical investigation of four cases of cerebellar glioblastoma, a rare tumor. The cases included three males and one female, from 33 to 67 years in age (mean 49 years). Tumor resection, postoperative irradiation and chemotherapy were performed in all cases. Two patients died of local tumor recurrence after 14 and 27 months. Another patient relapsed after 10 months; however, after additional tumor resection and second line chemotherapy, she remains disease-free 41 months after the initial treatment. The fourth patient has not relapsed in the 6 months since initial treatment. The histopathology of all cases was glioblastoma with pseudopalisading necrosis. However, low-grade glioma histopathology was found in three patients. All glioblastomas were immunopositive for p53 and immunonegative for epidermal growth factor receptor (EGFR) and isocitrate dehydrogenase 1 (IDH1). These adult cerebellar glioblastoma cases had similar clinical and pathological characteristics, and had different characteristics compared with supratentorial glioblastomas.
