Glioblastoma multiforme of the cerebellum: description of three cases

Abstract

Only 43 cases of glioblastoma multiforme of the cerebellum have been reported in the literature. This report is based on the findings of 3 cerebellar glioblastomas in a review of 1,206 consecutive confirmed cases of glioblastoma operated on between 1947 and 1977 at the Istituto Neurologico of Milan, giving an incidence of 0.24%. Clinical features are similar to those of any other fast-growing subtentorial tumour. Neuroradiological studies, including CAT, are of little help in predicting the exact nature of these tumours before surgery. A correct diagnosis can be reached only by microscopic examination. Histological patterns appear in no way to differ from those of cerebral glioblastoma. The biological behaviour of these tumours is in all respects identical to that of glioblastoma of cerebral hemispheres.
