Language cortex reorganization may occur in cerebral AVMs, CMs, and gliomas when lesions involve language cortex. However, the potential of reorganization for CM and glioma patients seems to be insufficient compared with AVM patients. For the difference of AVMs and CMs, the possible reason is that CMs have little Bneed^ for language reorganization. Meanwhile, for AVMs and gliomas, the difference should be regarded as AVMs have a greater capacity for language reorganization because language reorganization is needed in both AVMs and gliomas. More specifically, we speculate the difference might be attributed to the histopathological difference, development stage, duration of illness, lesion size, and hemodynamic effects. Lesion size is not the only reason leading to this difference, and even very small nidus can induce rightsided lateralization.
