  		Figure 1. A child with reversible leukoencephalopathy.T2 weighted axial images through the supraventricular regions (a) shows multiple hyperintensities in both occipital and frontal regions involving the cortex and subcortical white matter. Repeat T2 weighted axial image corresponding to (b) after 12 weeks shows normal imaging.

  		Figure 2. Residual changes in a child with hypertensive leukoencephalopathy.T2 weighted axial images through the lateral ventricles (a) shows multiple hyperintensities in both occipital and frontal regions involving the cortex and subcortical white matter. Three-dimensional time of flight (3D-TOF) MR angiogram (b) shows only spasm of both proximal middle cerebral arteries (arrows). Repeat T2 weighted axial image (c) corresponding to (a) after 12 weeks shows residual lesions in both frontal regions.

  		Figure 3. Leukoencephalopathy with left temporal bleed.T2 weighted axial image through the temporal lobe (a) shows hypointense lesion in the left temporal lobe (arrow) that shows a bloom effect on T2* weighted image (b) consistent with bleed.

  		Figure 4. Normal imaging in a child with acute hypertensive encephalopathy.T2 weighted axial image (a) through the ventricles shows no abnormality. Three-dimensional time of flight (3D-TOF) MR angiogram (b) shows spasm of the left proximal and distal middle cerebral arteries (arrows).
