EC Emergency Medicine And Critical Care

Posterior reversible encephalopathy syndrome (PRES) is a rare condition characterized by cerebral distress and typical radiological images. Here, we report a case of a 20-year-old male, a chronic renal failure patient on hemodialysis, who presented with status epilepticus accompanied by elevated blood pressure. MRI revealed parieto-occipital lesions with T2 hypersignal. The patient responded well to antiepileptic and antihypertensive treatment, with complete recovery of consciousness and hemodynamic stabilization. The aim of this case is to highlight the importance of considering PRES in suggestive circumstances, given the favorable outcomes observed in early-treated patients.
