Female, 55 years old, with a left temporal tumor, fMRI requested for language lateralization prior to surgery. All tested language paradigms produced reliable language related activity. The highest quality images were obtained with the sentence completion, word generation, and verb generation paradigms. Language cortical activation was strongly right dominant with all paradigms. Putative Broca's area activity localized to the right inferior frontal gyri, and putative Wernicke's area activity localized along the posterior aspect of the right superior temporal sulcus. Strong secondary language related activity was elicited in the right middle frontal gyri, along with robust right SMA activation.
Language related cortical activity is strongly right dominant.
