We report a case of bilateral perisylvian polymicrogyria, which was evaluated using diffusion tensor imaging (DTI) and tractography. On DTI tractography, fibers of the arcuate fasciculus (AF), which connects the posterior inferior frontal region and superior temporal gyrus were absent. It indicates that in cases of bilateral perisylvian polymicrogyria, compromised language skills might be associated with the absence of AF.
