Imaging Patterns of Toxic and Metabolic Brain Disorders

Illustration shows the most important general imaging patterns in toxic and metabolic brain disorders. White areas = areas of involvement. These include symmetric basal ganglia and/or thalami involvement (axial view) (A); symmetric dentate nuclei involvement (axial view) (B); prominent cortical gray matter involvement (axial view) (C); symmetric periventricular white matter involvement (with gray matter sparing) (axial view) (D); corticospinal tract involvement (axial view) (E); corpus callosum involvement (coronal view) (F); asymmetric white matter involvement (demyelinating disease pattern) (axial view) (G); parieto-occipital subcortical vasogenic edema (axial view) (H); and central pons involvement (axial view) (I).
