Metastatic tumors

Abstract

Experience in metastatic brain tumor localization utilizing radiomercury-labled chlormerodrin was presented. Correct tumor localization was achieved in 78% of 51 patients. The best results utilizing Hg 197 chlormerodrin were obtained if 3 to 5 hr. elapsed between administration of isotope and the scan. The location pattern of cerebral metastatic tumor defined by scan was different than reported by Kindt. It was concluded that no arterial distribution or lobe of cerebrum is immune but that regions are affected in proportion to their relative bulk and vascular supply. Results showing a tendency toward a cerebellar location are reviewed.
