Uncommon Tumor of Cerebellopontine Angle: Report of an Adult Medulloblastoma

Medulloblastomas are relatively common tumors of posterior fossa during childhood with a frequency of 23 - 30%. However, adult cerebellar medulloblastomas are relatively rare and constitute 0,4 - 1,0% of adult primary brain tumors. Cerebellopontine angle (CPA) is an atypical site for medulloblastoma. We present a 34-year-old male with a CPA medulloblastoma. We recommend appropriate surgical planning whether extending to midline structures or fourth ventricle. CPA medulloblastomas are infrequently reported at the CPA region and have to be considered for differential diagnosis of other intra-axial or extra-axial CPA tumors. Adjuvant radiotherapy and combined chemotherapy regimen should be added at the postoperative management.
