Posterior reversible encephalopathy syndrome

Case contributed by Dr Amr Mubarak

Patient Data

Age: 29
Gender: Female

MRI of the brain demonstrates increased T2 / FLAIR signal in the occipital, parietal and posterior frontal lobes bilaterally. It predominantly affects the sub-cortical white matter, and is not associated with restricted diffusion. 

Case Discussion

This case illustrates PRES, and although the distribution is certainly posterior, it often (as in this case) can be seen in locations other than the occipital lobes. Someone suggested it should be called PPPRES (predominantly posterior possibly reversible encephalopathy syndrome).
