Reversible posterior leucoencephalopathy syndrome mimicking low-grade glioma: differentiation by positron emission tomography.

摘要

Reversible posterior leucoencephalopathy syndrome (RPLS) typically presents with global encephalopathy, seizures, headache and visual symptoms and is often triggered by a hypertensive emergency. Neuroimaging shows reversible vasogenic subcorti-cal edema without infarction, preferentially of the posterior brain regions. In some patients, the RPLS lesions have a very asymmetrical and even unilateral distribution [1 ].
