Abstract:
The incidence of delayed radiation necrosis is reported to be 0.5% to 5%. Recently, the incidence of delayed radiation necrosis has been increasing due to three major causes. Firstly, the radiation dose is increasing to treat malignant brain tumors aggressively. Secondly, new diagnostic tools such as high resolution brain CT and magnetic resonance imaging enable the precise detection. Finally, survival time after radiation therapy is prolonged so that delayed radiation effect comes out. We experienced one case of delayed radiation necrosis at the temporal lobes after total 11,000 rads irradiation for nasopharyngeal cancer. We report this case with brief reviews of the articles.
