BACKGROUND:

Reversible posterior encephalopathy syndrome is a rare entity. It occurs most frequently in the third trimester and puerperium, associated with cases of preeclampsia-eclampsia and Hellp's syndrome. Radioimage studies are basic for its diagnosis and must be differentiated from other neurological pathologies, due to its different treatment and prognosis.

CASES REPORT:

This study presents two cases of reversible posterior encephalopathy syndrome with different risk factors for its presentation (septic shock, multiple organ failure and preeclampsia-eclampsia syndrome). The diagnosis is based on the underlying disease, clinical suspicion and magnetic resonance findings. In both cases, most of the symptoms related to eclampsia. The timely treatment and correction of fluid-electrolyte imbalance, acid-base, sepsis and volume overload are decisive in reversing the condition and preventing the evolution of the syndrome. The diagnosis of reversible posterior encephalopathy was corroborated by radiological studies. The patients withdrew from the care unit with complete remission of the neurological symptoms.

CONCLUSIONS:

Reversible posterior encephalopathy is a rare entity, of unknown prevalence in the pregnant patient, which occurs for different reasons, with full recovery, but which requires a specific diagnosis and treatment.
