1 A, Coronal SS-FSE T2-weighted image in a 30-gestational-week-old fetus demonstrates dysplastic-appearing Sylvian fissures with multiple abnormal small infoldings of the cortex (black arrows) consistent with perisylvian polymicrogyria. A, Coronal SS-FSE T2-weighted image in a 30-gestational-week-old fetus demonstrates dysplastic-appearing Sylvian fissures with multiple abnormal small infoldings of the cortex (black arrows) consistent with perisylvian polymicrogyria. Absence of the septum pellucidum is present, and was noted on the prenatal sonogram. A hyperintense focus (white arrow) is seen adjacent to the left lateral ventricle in the region of the caudate head, consistent with an area of injury.B, Axial images confirms perisylvian polymicrogyria (black arrows) and periventricular cyst (white arrow).
