Patient 6.

A, Sagittal T1-weighted image (500/14/4) shows the relationship between the left-sided, central AVM and the precentral knob.

B, Movements of the right foot show the expected response in the left paracentral lobule (contralateral M1) with additional activation in bilateral SMAs.

C, Right-hand movements do not elicit activation in M1 but there is prominent signal in bilateral SMAs. Note additional activation in ipsilateral dorsal premotor areas and in the contralateral parietal areas and CMA.
