After analyzing the results vis-à-vis the site of the brain metastasis, the site of the primitive tumour and the surgical treatment administered; emphasis is given to the importance of the advent of the CT scan which has permitted a more accurate selection of the patients resulting in improvement in operative mortality and average survival time which at present is one year.
