Disease progression and therapy during a 3-year period were followed up at different time points： before and after reoperation, after radiation therapy, and 1 year after irradiation. During the whole 3-year follow-up period, the patient exhibited no neurological deficits while functional magnetic resonance imaging revealed different topologies of the language-related brain network. During disease progression and after irradiation, the language-related brain network was extended or completely transferred to the nondominant （right） hemisphere. In addition, after reoperation and 1 year after irradiation, language areas were primarily found in the language dominant （left） hemisphere. Our results suggest a high level of adaptability of the language-related cortical network of the bilateral hemispheres in this low-grade glioma patient.展开更多
