Clinical and imaging course of posterior reversible encephalopathy syndrome in a patient with endocarditis and arterial hypertension

Posterior reversible encephalopathy (PRES) is a clinical syndrome characterized by headaches, seizures, cortical blindness, and altered mental status up to coma and by a radiological syndrome defined by edematous alteration on Magnetic Resonance Imaging (MRI)—Scans of the white matter. In the following, we present the case of a 73 years old post-operative patient with PRES in the context of hypertension and endocarditis with E. coli. The initial presentation included a series of seizures, sopor, and cortical blindness. In MRI-Scans a marked cerebral edema could be identified. After successful treatment of underlying conditions, the patient has made a good recovery. However, homonymous hemianopsia towards right due to laminar necrosis in the left occipital lobe remained as a residuum.
