Predominantly left hemisphere activations in a patient with a low-grade glioma in the left hemisphere. Panel (A): a raw functional image with a notable absence of activation in the left frontal region corresponding to Broca’s area. The absence of activation may be related to artifact and edema from prior resection in the area. Panel (B): Language activation consistent with Broca’s area during pre-surgical fMRI. Activations in the right hemisphere were much less significant in this patient.
