title: Radiation necrosis of the brain. Neuroradiological considerations with computed tomography.
abstract: In cases with radiation necrosis of the brain, conventional neuroradiological examinations usually demonstrate only an avascular mass lesion impossible to differentiate from intracerebral tumor or hemorrhage. Computed tomography, performed in addition to angiography in three cases, consistently demonstrated the radiation necrosis as a low density area exhibiting enhancement following infusion of contrast medium. The importance of recognizing radiation necrosis as a differential diagnosis to brain neoplasm is emphasized.
