Fig 2. Patient 2. Morphologic MR imaging. A and B, respectively, Axial T1 (TR=165 ms, TE=4.2 ms) and axial FLAIR (TR=10 000 ms, TE=155 ms)-weighted MR images show multiple confluent oval well-defined lesions, isointense to CSF, with no mass effect in the left superior and inferior parietal lobules and in the posterior part of the left middle (T2) and inferior (T3) temporal gyri. B, FLAIR-weighted MR image shows a hypersignal interspersed among the cystic dilations, which could correspond to gliosis. C, fMRI (language task) shows a cortical activation in the superior part of the left inferior parietal lobule (Broadmann area 7, arrowhead) in regard to the lesions seen on the morphologic MR imaging. There is also a cortical activation of the left Broadmann area 44 (F3, white arrow), which demonstrates the lateralization of language to the left hemisphere. D, The tractography shows a decrease of white matter fibers in the pathologic areas (white arrow) compared with the healthy side.
