Figure 1: Subependymal heterotopia-magnetic resonance images.(a) T1-weighted axial section showing multiple subependymal nodules (arrows), isointense to cortical gray matter, symmetrically lining the lateral walls of the lateral ventricles. (b) T2-weighted coronal section demonstrating heterotopic nodules along the paratrigonal region of both ventricles. (c) Axial inversion recovery magnetic resonance image showing bilateral nodules indenting the walls of ventricles (arrows)
