摘要Because functional magnetic resonance imaging can be used for dynamic observation of functional cortical changes after brain injuries, we followed up functional magnetic resonance imaging manifestationsof a language-related brain network in a low -grade glioma patient. Disease progressionand 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 revealeddifferent 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, languageareas were primarily found in the language dominant (left) hemisphere. Our results suggest a highlevel of adaptability of the language-related cortical network of the bilateral hemispheres in thislow -grade glioma patient.
