Axial brain MRI images. Axial T1-weighted images [A-C] demonstrate
bilateral hypointense lesions in the ventromedial prefrontal cortex that
are more extensive to the right side, where lesion also encompasses the
adjacent orbitofrontal cortex [arrows in A]. There is also bilateral
involvement of the anterior cingulate cortex and the genu of the corpus
callosum [B]. The left lateral portion of the prefrontal cortex is
spared; but to the right there is extension of the hypointensity
especially to the dorsolateral cortex [these aspects are more evident in
B and C].

His brain MRI scan revealed bilateral orbitofrontal (OFC) and ventromedial prefrontal lesions that were more extensive to the right side (Figures 1, 2 and 3).
Sagittal brain MRI images. Sagittal T1-weighted images [A and B] show
hypointense lesions in the genu of the corpus callosum [arrow in A] and
anterior cingulate cortex [arrowhead in A]. The damage to the right
medial prefrontal cortex [A] and the adjacent dorsolateral prefrontal
cortex [arrow in B] is more clearly visible, while the ventrolateral
cortex is partially preserved near the sylvian fissure.
