title: [A case of chondroblastoma with intracranial extension].
abstract: A case of chondroblastoma with intracranial extension from middle cranial base is reported here. Chondroblastomas usually arise from the epiphysis of long bone. Intracranial chondroblastomas are very rare and only 14 cases have been reported. Histological feature of this tumor is to have numerous multinucleated giant cells resembling the giant-cell tumor. But this case has the typical features of chondroblastoma in the histological, immunohistochemical, and electron microscopical studies.
