FIG 8. Short-TI inversion recovery images. Dotted arrows in the left striatum show the supposed pathway of lesional distribution along the putaminocaudate gray matter bridges and nucleus accumbens septi.

A, Coronal image shows the anatomic connections between the caudate head and the putamen. Solid arrow and arrowhead in the right cerebral hemisphere indicate the putaminocaudate gray matter bridges and the nucleus accumbens septi, respectively.

B, Solid arrows in the left putamen on this axial image show the direction of lesional extension observed in our study.
