Transient splenial lesion after recovery of cerebral vasoconstriction and posterior reversible encephalopathy syndrome: a case report of eclampsia.
We describe a 34-year-old eclamptic woman with transient splenial lesion (TSL) after reversible cerebral vasoconstriction (RCV) and posterior reversible encephalopathy syndrome (PRES). She developed a headache, generalized convulsion and severe hypertension at an uncomplicated virginal delivery. Brain MRI disclosed T2-hyperintensity lesions in the posterior circulation territories. Two weeks later, T2-hyperintensity lesions had vanished. MR angiography (MRA) revealed segmental vasoconstriction in the right posterior, left internal and middle cerebral arteries. At one month after onset, MRA was normalized. T2-weighted imaging depicted asymptomatic isolated TSL. These radiological changes of the present patient highlighted the serial relationship between PRES, RCV and TSL in eclampsia.
