FIG 3. Mixed curvilinear/nodular subcortical heterotopia.

A, Axial spin-echo (2500/80) image shows nodular heterotopia (white arrows) in the periventricular white matter bilaterally. No cortical connection is seen at this level.

B, Axial spin-echo (2500/80) image obtained at a higher level shows that the heterotopia (white arrows) are contiguous with the cortex bilaterally.
