1 MRI. MRI. (A1–A2) Patient 6 with simple PNH, (B1–B2) patient 10 with plus PNH. (A1) Sagittal TSE T2 WI shows multiple periventricular nodules (arrows). The signal from the nodules is homogeneous and consistent with grey matter. (A2) Axial TSE-IR T1 WI shows bilateral, asymmetric isointense nodules along the outline of both lateral ventricular walls (arrows). The overlying cortex is normal. (B2) Axial TSE T2 WI displays subependymal heterotopic grey matter along the posterior part of the floor of the right lateral ventricle, associated with subcortical heterotopia and focal cortical dysplasia. (B1) Coronal SE T1 WI shows a large, single periventricular heterotopic grey matter nodule (arrow) at the level of the right trigone that is enlarged. G d’Orsi et al.
