Posterior reversible encephalopathy syndrome after depletive lumbar puncture: A case report

Introduction: Posterior reversible encephalopathy syndrome is a rare entity. Its pathophysiology is still poorly understood.; Case presentation: We report the case of a 69-year-old White European woman who presented complete and proportional right hemiplegia, confusion, deviation of her head and eyes to the right, cortical blindness, and generalized tonic-clonic seizure 12 hours following a depletive lumbar puncture. Emergency cerebral magnetic resonance imaging showed bioccipital and left-side basal ganglia hyperintensities in the fluid attenuated inversion recovery and the diffusion-weighted images suggesting a radiological diagnosis of posterior reversible encephalopathy syndrome.; Conclusions: The diagnosis is established on clinical and radiological signs. This is the first report of this kind in the literature. We present a case of posterior reversible encephalopathy syndrome after depletive lumbar puncture and we discuss the pathophysiology. © 2014 Grelat et al.; licensee BioMed Central Ltd.
