A Case of Posterior Reversible LeukoEncephalopathy Syndrome in a Woman with Renal Artery Stenosis

초록

Background: Posterior reversible encephalopathy syndrome (PRES) is characterized by a clinical and radiological entity with seizure, headache, hypertension, visual loss and encephalopathy with neuroimaging findings of reversible vasogenic subcortical edema. The co-morbid conditions is hypertension, renal disease, autoimmune disease, eclampsia and transplantation. Methods: A 42-year-old woman was admitted to our hospital with complaint of sudden onset of seizure. Her blood pressure is 210/110mmHg and mental is drowsy state. After this episode she compained of blindness for a few days. Brain MRI showed multifocal edema in bilateral occipital lobe, frontoparietal lobe. In several hypertensive work-up studies, renal doppler ultrasonography showed stenosis of right renal artery. Results: Segmental stenosis in right renal artery was demonstrated by renal angiography. We performed stent insertion in renal artery narrowing portion. Her blood pressure was maintained less than 140/80mmHg without the antihypertensive drugs. Conclusion: PRES was induced by renal hypertension and it’s cause was right renal artery stenosis. Here we report a rare case of renal artery stnenosis with complication of PRES.
