Fluid-attenuated inversion recovery images (a,b) of the brain show signal changes in the bilateral occipital subcortical white matter, pons, medulla and left cerebellum. Intramedullary T
2 hyperintensity with mild cord expansion (c-e) is seen in the entire spinal cord with extensive leptomeningeal enhancement on the post-contrast study (f). Angiogram (k,l) shows right proximal renal artery stenosis (red arrow in l) and focal area of stenosis in the descending aorta. An MRI repeated after 4 weeks shows complete regression of the signal changes in the brain and the spinal cord (g-j).

An MRI (Figure 1) showed multifocal T 2/fluid-attenuated inversion recovery hyperintensities involving the bilateral putamen, subcortical white matter in bilateral occipital lobes, pons and medulla.
