Patient 3.

A, Sagittal T1-weighted image (500/14/4) shows an AVM in the right precentral gyrus, involving the anatomically expected area of hand representation.

B and C, As compared with the unaffected left hemisphere (B), the hand representation in the affected right hemisphere (C) is displaced medially within the precentral gyrus. Additional activation within the ipsilateral M1 is detected. The functional displacement does not follow the structural distortion induced by the underlying disorder. Note additional activation in bilateral supplementary motor (arrows, upper right image in C) and parietal areas.
