The authors report on the results obtained on a series of 325 patients operated on for single brain metastasis at the Institute of Neurosurgery of the University of Rome during the period 1951-1979. 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.
