Abstract
Twentysix cerebral metastatic tumours treated with the Gamma knife employing a large single dose were followed by repeated clinical and CT examinations. In most cases Gamma knife surgery was the only treatment. The follow up time has been longer than 6 months with a median follow up of 9 months. In all but one of the cases a remarkable progressive shrinkage of the tumour started 2–4 months after the therapy. The therapeutic results indicate that radiosurgery used even as the only form of treatment is the best treatment alternative for cerebral metastasis presently available.
