[Reversible posterior leukoencephalopathy syndrome accompanied by HELLP syndrome and eclampsia: a case report]

We report a case of reversible posterior leukoencephalopathy syndrome accompanied by HELLP syndrome and eclampsia. A 30-year-old woman complained of diminution of visual acuity and eclampsia. Laboratory data revealed hemolysis, elevated liver enzyme and low platelets. CT showed low density areas in the bilateral occipital cortex. T1-weighted images showed a low signal intensity and T2-weighted images showed a high signal intensity in the occipital cortex bilaterally. Magnetic resonance angiography showed stenotic change in the intracranial artery. An operation was performed and significant improvement was seen in her visual function and MRI and MRA returned to normal on a month after operation. The mechanism of a reversible posterior leukoencephalopathy syndrome was discussed.
