Female, 21 years old, with epilepsy. Presurgical planning fMRI is requested. Sensorimotor cortical activation of the hand, foot and face maps as expected along the pre- and post-central gyri.Of the tested language paradigms, the most reliable language-related cortical activation is seen with the word generation, verb generation, and sentence completion paradigms. Language is overall left dominant. On one trial of the word generation paradigm, a substantial right sided Wernicke's contribution was seen, but the remaining paradigms show left dominant activation, and Broca's area activity is only seen on the left. Broca's area is identified in the inferior frontal gyrus (predominantly pars triangularis). Wernicke's area is identified along the posterior aspect of the superior temporal sulcus.The visual stimulation paradigm elicits bilateral activity along the inferior calcarine sulcus of the occipital lobes.A set of conventional FLAIR images of the brain was also obtained and these show no obvious or discrete parenchymal lesions.
Successful functional MRI for surgical planning purposes. Sensorimotor cortical activation maps as expected along the pre- and postcentral gyri.Language is left dominant with Broca's and Wernicke's areas located in their customary locations.Visual cortical stimulation maps along the calcarine sulcus bilaterally.
