Figure 39-1. Axial CT without contrast 1 day after cardiac arrest demonstrating loss of distinction between gray and white matter structures throughout the cerebral hemispheres. The patient remained comatose and became vegetative.
Figure 39-2. Axial CT without contrast showing arterial borderzone infarctions between the middle and posterior cerebral arteries after brief cardiac arrest. The patient had Balint syndrome.
Figure 39-3. Axial T2-weighted MRI showing striatal damage after anoxia from suffocation. The pallidum is relatively spared, in contrast to typical cases of carbon monoxide poisoning (see Fig. 39-5).
Figure 39-4. Axial T2-fluid-attenuated inversion recovery (FLAIR) MRI of delayed postanoxic leukoencephalopathy in a patient who had recovered after drowning and deteriorated 2 weeks later.
Figure 39-5. Axial CT without contrast of a 30-year-old woman who attempted suicide by carbon monoxide inhalation. Small areas of decreased attenuation are seen in the pallidum bilaterally (arrows). The only neurologic residua were a mild defect in retentive memory.
Figure 39-6. T2-weighted MRI showing the typical lesion of central pontine myelinolysis in an alcoholic patient.
