Radiation necrosis (brain sections)

Hematoxylin and eosin stained sections from a craniotomy specimen in a 55-year-old patient with cerebral radiation necrosis. Sections demonstrate the characteristic findings of radiation necrosis: confluent areas of coagulative necrosis, reactive astrocytes with bizarre nuclei, marked thickening and fibrinoid changes in blood vessels, and areas of hemorrhage. (A) 10 X, (B) 20 X, and (C) 40 X. (Contributed by Dr. Michael Glantz.)
