Abstract
Radiation necrosis is a delayed complication of cranial irradiation, typically presenting as a single intracerebral mass that is radiographically indistinguishable from recurrent tumor. We describe 6 patients with a distinct radiographic syndrome of multifocal enhancing lesions on magnetic resonance images, and their variable clinical courses: some fluctuating, some spontaneously resolving, and some demonstrating fulminant progression to frank necrosis.
