Images obtained in patient 3 with HZV-induced progressive outer retinal necrosis preceding retrobulbar optic neuritis, CNS extension, and eventual demise.A, Coronal T2-weighted gradient-echo image suggests hemorrhage in the right lateral geniculate body, with increased signal intensity involving the optic radiation through the temporal lobe (arrowhead) and extending caudad along the lateral midbrain (large arrow) to the cerebellum (small arrow).B, Axial T2-weighted turbo spin-echo image shows increased signal intensity along the right optic tract (white arrow) and lateral geniculate body (black arrow).C and D, Proton density–weighted images demonstrate abnormally high signal intensity along the right hemipons (thin arrow in C), right midbrain, and superior colliculus (arrow in D), occipital (visual) cortex (thick arrow in C), and optic radiation in the temporal lobe (arrowheads in D).E, T1-weighted contrast-enhanced image shows enhancement in similar regions: optic tract (white arrow) and lateral geniculate body (black arrow). Postmortem immunofluorescence stains (not shown) demonstrated HZV in these areas. Robert J. Bert et al. AJNR Am J Neuroradiol 2004;25:1722-1729 ©2004 by American Society of Neuroradiology
