With 12 FiguresWhile in large general autopsy material the frequency range of metastatic tumors of the brain is from 13.5 to 87 per cent, in pure neurosurgical material this same frequency is evaluated from 8.5 to 7% (quoted from StSrtebecker).Sarcomas are metastatising into the brain with a relatively high frequency (Giirtner, 8.2%; Henschen, 8.9%; StSrtebecker, 5.7%).Sareomatous metastasis into the brain stem is by itself a very uncommom ioealization. This well known rarity, as well as the peculiarity of the arteriographie pattern of the tumor mass in the following ease prompted this presentation.Case Report Acta Neurochirurgica, Vol, X, Fast. 2. 8
