Stereotactic radiosurgery (SRS) becomes more widely used in treatment of patients with intracranial tumors. In spite of low invasiveness this method produces risk of development of radiation-induced complications including symptomatic focal necrosis. Authors report a case of radiation-induced necrosis occurred in a patient treated for benign glioma using Leksell Gamma-Knife. Morphological features, risk factors, incidence, differential diagnosis and treatment of cerebral radiation-induced necroses are briefly discussed in this article.
