Female, 47 years old, with known cavernous malformation, speech and motor assessment for surgical planning. Sensory motor cortical activity maps as expected along the pre- and post central gyri. Cortical activation related to facial/tongue movement maps immediately anterior to the known left parietal opercular lesion.Reliable language-related activation was achieved with all the attempted language paradigms. Language is left dominant. Putative Broca's area activity is seen within the pars opercularis and pars triangularis on the left. Putative Wernicke's area activity is seen within the posterior superior left temporal gyrus.
1. Sensory motor cortical activation related to the face/tongue maps immediately anterior to the known lesion within the left parietal operculum.2. Language functional activation is left dominant. Broca's and Wernicke's areas are identified and found to be well separated from the lesion.
