TORRES, Moisés Ulises et al. Posterior reversible encephalopathy syndrome: Report of a fatal case and analysis of predictive factors of a poor prognosis. Biomédica [online]. 2017, vol.37, suppl.1, pp.12-19. ISSN 0120-4157.  https://doi.org/10.7705/biomedica.v37i2.3299.

Posterior reversible encephalopathy syndrome is an illness with multiple causes and distinctive clinicalradiological characteristics that should be known by intensivists and emergency room physicians for a timely diagnosis and treatment. A fatal case of posterior reversible encephalopathy syndrome is presented, and the risk factors related to the outcome are identified.

A 60-year-old man without a relevant medical history arrived at the emergency room presenting with depressed consciousness, seizures, and high blood pressure. Tomographic images revealed a posterior cerebellar hematoma. Resonance images showed ischemic zones, vasogenic edema from the thalamus to the brain stem, middle cerebellar peduncles, deep white matter of the cerebral hemispheres, and zones of hemorrhagic transformation. Despite medical-surgical management, the patient died. The risk factors described as the cause of the fatal outcome were identified. This case demonstrates that posterior reversible encephalopathy syndrome can occur without triggering risk factors and highlights the need for early recognition to establish an appropriate intervention to avoid injury or a fatal outcome. Cases of posterior reversible encephalopathy syndrome provide opportunities to investigate the susceptibility for the development of this condition and to establish appropriate preventive measures.
