Images at the level of the basal ganglia and sylvian fissure in a patient with hyperintensity on FLAIR images.A, Contrast-enhanced FLAIR image shows increased signal intensity in the basal ganglia and PLIC bilaterally, left thalamus, and left periventricular white matter, as well as the temporoparietal and occipital sulci.B, Contrast-enhanced T1WI shows no corresponding enhancement.C and D, DW image (C) and ADC map (D) show restricted diffusion is seen in the left periventricular white matter, right basal ganglia, and bilateral PLIC.E and F, Contiguous FLAIR images show increased signal intensity in the midbrain and medial temporal lobes bilaterally, as well as in the right temporal lobe peripherally. Hyperintensity is again shown in the sulci, signifying WNV meningoencephalitis. Muhammad Ali et al. AJNR Am J Neuroradiol 2005;26: ©2005 by American Society of Neuroradiology
