title: Brain metastasis of unknown origin.
abstract: From 1973 to 1984, 119 patients presented to the Department of Neurosurgery, Royal Victoria Hospital, Belfast, with brain metastases, the primary sites of which remained unknown in 33 cases one month after discharge. About half of these cases were solitary and neurological lateralising signs were the commonest presentation. Of those cases in which surgery was performed, the majority remained improved one month after surgery. The one month mortality rate was only 3%. This study shows that with aggressive and appropriate treatment including surgical excision or decompression in solitary cases, an improved quality of life in the immediate postoperative period can be achieved in this particular group of brain metastases. A small number of patients remained alive and well after 6 months.
