    Author: Kato K, Yoshida J, Kageyama N.
    Journal: No Shinkei Geka; 1986 Jul; 14(8):981-7. PubMed ID: 3018607.
    Abstract:
    Clinico-pathological findings of CSF dissemination which was diagnosed on CT scan, were studied on 13 cases of glioblastoma and 9 cases of medulloblastoma. The type of CSF dissemination and the prognosis of patients were both different between glioblastoma and medulloblastoma. In the former, the dissemination was predominantly in ventricular walls and in the latter, in basal cisterns. The mean survival time after the diagnosis of dissemination is 6 months of glioblastoma as compared with 13 months of medulloblastoma. The Pathological studies show that subependymal and/or subpial infiltration of tumor cells, and thickness of arachnoid membrane by marked mesodermal reaction were demonstrated in cases of glioblastoma. On the contrary, tumor cells of medulloblastoma grow markedly in the subarachnoid space and/or on the ependymal layers. From these pathological findings of CSF dissemination, it will be resulted that the prognosis of glioblastoma is much more poor that of medulloblastoma.
