Male, 32 years old, with headache and right posterior frontal tumor. Sensorimotor cortical activation of the hand, foot and face maps as expected along the pre- and post-central gyri. Activation related to the face maps to a location one gyrus posterior to the patient's right frontal lesion.Of the tested language paradigms, the most reliable language related cortical activation is seen with the sentence completion and verb generation paradigms. Language is left dominant. Putative Broca's area activity is identified on both paradigms in its customary location of the left inferior frontal gyrus, primarily pars opercularis with some activity in pars triangularis. Putative Wernicke's area activity is identified only on the sentence completion paradigm in its customary location along the left superior temporal sulcus. There does not appear to be any significant language related activity in the vicinity of the patient's right frontal lesion.
1.Technically successful functional MRI for presurgical functional mapping.2.The sensorimotor cortex is adequately visualized in its customary location.3.Language is left dominant with no significant language related activity identified in the vicinity of the patient's right frontal lesion.
