Periventricular nodular heterotopia
Related syndrome:
Brain MRI scan; axial section. Typical classic bilateral periventricular nodular heterotopia in a woman with a missense mutation of the FLNA gene. Bilateral nodules of subependymal heterotopia are contiguous and rather symmetric, extensively lining the ventricular walls (white arrows). Patients with periventricular heterotopia different from that reproduced in this picture have very low chances of carrying a mutation on the FLNA gene.
