Reversible posterior leukoencephalopathy syndrome.

Reversible posterior leukoencephalopathy syndrome (RPLS) is a neurological disorder characterized by signs of posterior cerebral edema upon radiographic examination. RPLS has been strongly associated with abrupt and significant elevations in blood pressure or the administration of immunosuppressive drugs. Here, we report a case of RPLS occurring in a 30-year-old-mother with a presumed amniotic fluid embolism subsequent to delivery by cesarean section. On the fifth day after the initial successful resuscitation from the cardiorespiratory collapse, she manifested generalized seizure activity and abnormal radiological findings, which were found to be consistent with RPLS. Through our experience, we have suggested that RPLS might occur more easily at lower blood pressures than has been previously recognized. It is important to consider the lower limit at which blood pressure is controlled, especially if accompanied with fever.
