Reversible posterior leukoencephalopathy syndrome (RPLS) is an acute form of cerebrovascular injury that has been described recently in the setting of uncontrolled hypertension, puerperal eclampsia, or treatment with certain immunosuppressive drugs, including cyclosporine. It is reversible if treated promptly. Two patients with systemic lupus erythematosus (SLE), renal failure, and uncontrolled hypertension developed acute cerebrovascular symptoms; one had seizures and the other had headache and blurred vision. Both patients showed abnormal predominantly posterior lobe findings on neuroimaging films. The patients' symptoms and imaging abnormalities resolved completely with prompt correction of their hypertension and concomitant treatment with corticosteroids. RPLS should be recognized in SLE patients with uncontrolled hypertension and renal failure who present with headaches, seizures, cortical blindness, and other visual abnormalities. Prompt treatment with control of hypertension and withdrawal of precipitating drugs may be most important and can prevent permanent neurologic damage.

Reversible posterior leukoencephalopathy syndrome (RPLS) is a rare clinical-radiologic syndrome. There are reports that RPLS may be associated with cancer therapy including some chemotherapy drugs and antiangiogenic drugs. This paper reported a case of RPLS induced by apatinib, a vascular endothelial growth factor receptor 2 (VEGFR-2) tyrosine kinase inhibitor. A 47-year-old cervical cancer patient was administered apatinib, and 3 months later, headache, dizziness, blurred vision, and hypertension appeared. She was diagnosed with RPLS by nuclear magnetic resonance imaging (MRI). After apatinib discontinuation and normotensive treatment, her symptoms completely reversed. Antiangiogenic drugs potentially damage the balance of the blood-brain barrier by directly injuring vascular endothelial cells, resulting in the occurrence of RPLS. This case is the first report of RPLS induced by apatinib.
