&NA;Gamma knife surgery employing a central dose of 70 Gy and a peripheral dose of 25 Gy caused progressive necrosis and shrinkage of a recurrent solitary metastasis of a cerebral hypernephroma, as verified by computed tomographic scan 2 and 4 months after treatment. Gamma knife surgery was an effective palliative treatment for this cerebral metastasis and was an alternative to craniotomy with microsurgical removal. (Neurosurgery25:802‐804, 1989)
