Computed tomography of intracerebral leukemic masses

Abstract

Five patients with differing types of leukemia had clinical symptoms of a localized intracerebral leukemic mass. Computed tomography (CT) demonstrated a mass of equal or increased density relative to normal brain; a zone of surrounding edema was variable. In each case, the mass showed evidence of relatively uniform contrast enhancement. CT appearance of leukemic masses is consistent and quite different from the findings in other central nervous system complications of leukemia and its aggressive treatment.
