Male, 17 years old, with medically refractory epilepsy. Functional MRI requested for localization of language, motor and vision. Sensorimotor cortical activation of the hand, foot and face maps as expected along the pre- and post-central gyri. Of note, only left-sided foot sensorimotor activation is seen. Failure to visualize right-sided activity on the right may reflect variable patient effort or a technical artifact.Of the tested language paradigms, the most reliable language related cortical activation is seen with the word generation and sentence completion paradigms. Language is left dominant.Activation corresponding to the putative Broca's area is seen within the left inferior frontal gyrus (pars opercularis and pars triangularis). Activation corresponding to the putative Wernicke's area is represented by 2-3 foci within or along the posterior aspect of the left superior temporal sulcus.Passive visual cortical stimulation results in activation as expected along the bilateral calcarine sulci.
