title: Reversible posterior leukoencephalopathy syndrome secondary to systemic-onset juvenile idiopathic arthritis: A case report and review of the literature.
abstract: Reversible posterior leukoencephalopathy syndrome (RPLS) is a clinical syndrome based on changes in clinical imaging, and it has been reported to mainly occur in adults. However, it has been recently discovered that RPLS is also prevalent in infant patients, particularly in those using glucocorticoids, immunosuppressant medications and cytotoxic drugs. The current study presents a 5-year-old male with a previous diagnosis of systemic-onset juvenile idiopathic arthritis (SoJIA) and macrophage-activation syndrome who developed posterior reversible encephalopathy syndrome during treatment with glucocorticoids, disease-modifying antirheumatic drugs and biological agent (etanercept) therapy. After ~5 days of treatment, the patient made a complete clinical recovery; the magnetic resonance imaging reviewed 2 weeks later showed that the previous hyper-intensity signal had disappeared and the multiple lesions in the brain had been completely absorbed. The case report shows that, conforming to recent literature, SoJIA in infants should be considered a risk factor for developing RPLS. The clinical manifestations of the disease are multiple, but usually reversible, and the patients mostly have a good prognosis. Rapid diagnosis and treatment is essential as early treatment may prevent progression to irreversible brain damage. By increasing the awareness of RPLS, the patient care may improve and further insight may be gained.
