[Neuroradiological image analysis and prognostic factors of malignant gliomas in the cerebral hemisphere of adults].

54% cases of malignant gliomas followed more than 2 years were studied about prognostic factors focusing on neuroradiologic image analysis in the two groups classified survival cases over 2 years and dead cases within 2 years after surgical treatment. 21% cases of malignant gliomas having tumor infiltration or edema to contralateral hemisphere on CT and MRI before treatment were dead within 2 years. 80% of recurrent malignant gliomas had abnormal shadow on CT due to tumor recurrence in primary tumor site or ventricular wall and/or contralateral hemisphere continuing with there. Remote metastasis discontinuing with primary site was demonstrated in only 20% of them. Over 90% of glioblastoma multiforme showing irregular tumor stain with arteriovenous fistula on angiogram were dead within 2 years, whereas in the cases without tumor stain the alive cases more than 2 years increased comparing with those having tumor stain.
