CT (axial) obtained one hour after DSA shows bilateral symmetrical contrast enhancement in parieto-occipital cortex and subarachnoid spaces, as well as in thalami.

An emergency CT brain scan was requested and revealed bilateral symmetrical contrast enhancement in parieto-occipital cortex and subarachnoid spaces, as well as in thalami (Figure 1).
Brain MR (axial images) obtained 2 days after angiography. T2 and FLAIR images (a, b) show bilateral symmetrical hyperintensities in basal ganglia, in parieto-occipital cortex, and in splenium of corpus callosum. DWI and ADC images (c, d) demonstrate restricted diffusion in the same areas.

DWI and ADC images demonstrated restricted diffusion in the same areas (Figure 2). Daily hemodialysis was performed for the next 3 days, and she was treated with dexamethasone.
Follow-up brain MR-T2 (a), FLAIR (b), and DWI (c) axial images obtained in another facility 1 month after the initial MR shows complete resolution of the lesions.

One month after discharge follow-up, brain MRI did not show any residual lesion, which correlates with the complete recovery (Figure 3).
