A 45-year-old man who developed brain radionecrosis in the right frontal and left temporoparietal lobes after receiving whole brain radiotherapy and stereotactic radiosurgery for primary central nervous system lymphoma. Since high dose steroid treatment failed and he declined to undergo surgery, he was referred to hyperbaric oxygen (HBO) therapy. Both clinical and radiological findings improved after HBO therapy. Steroid requirements were also reduced. HBO therapy may have a potential value in treatment of brain radionecrosis.
