Female, 74 years old, with brain tumor, functional mapping requested for surgical planning. Sensorimotor cortical activation of the hand, foot and face maps as expected along the pre- and post-central gyri. Of note, the foot movement paradigm elicited numerous areas of apparent cortical activation throughuot the hemispheres in addition to the expected sites which is of uncertain significance and potentially artifactual. Of the tested language paradigms, the most reliable language related cortical activation is seen with the word generation, verb generation, and sentence completion paradigms. All paradigms show similar results. Language is left dominant. The putative Broca's area is identified in the left inferior frontal gyrus, primarily pars orbitalis. The putative Wernicke's area is identified along the posterior aspect of the left superior temporal sulcus.
Successful functional MRI for sensorimotor and language cortical mapping.
