Plate 4

MRI scan of a patient with a surgical excision in the right HG;

illustrated are planes of section oriented horizontally (A), sagittally (B),

and coro-

nally (C). The left side of panels A, B, and C show the patient

’s scan alone, with an

arrow

indicating the region of excision/undercutting. The images on the

right side

of panels A, B, and C show the patient’s scan coregistered with an anat

omical probabilistic map of HG derived from normal individua

ls (Ref. 44).

The

crosshairs

indicate the same position in the standardized space as the

arrow

. Note the correspondence between the position of HG as det

ermined from

the map and the patient’s partially excised HG region. The

ye

llow box

in panel C indicates the region of the removal pictured in close-up in panel D

, which

illustrates the transition from intact, to undercut, to fully excised tissue (coronal sections taken at 3-mm intervals, posterior

to anterior).

Arrows

again

correspond to the

crosshairs

in the other panels and indicate the location of the HG region.
