Case Discussion
Posterior reversible encephalopathy syndrome is a condition due to breakdown in the auto-regulation of blood pressure in the posterior circulation resulting in vasogenic edema because of break in blood brain barrier, usually in parieto-occipital lobes.
The patient found to have high blood pressure of 200/160 mm Hg on admission and the imaging features were consistent with posterior reversible encephalopathy syndrome.
