Posterior Reversible Encephalopathy Syndrome And Primary Sjogren'S Syndrome

Posterior reversible encephalopathy syndrome is a nebulous disorder triggered by a number of conditions, mostly hypertensive crisis, renal insufficiency, and immunosuppressive therapy. Other possible etiologies include eclampsia, transplantation and infections. The association of posterior reversible encephalopathy syndrome with autoimmune diseases has been rather intriguing. We herein describe an unusual case of posterior reversible encephalopathy syndrome in a patient with primary Sjogrenu0027s syndrome, hypertension and lung infection. This is probably the second reported case associating posterior reversible encephalopathy syndrome and primary Sjogrenu0027s syndrome. If the posterior reversible encephalopathy syndrome was triggered by primary Sjogrenu0027s syndrome itself or by its comorbidities remains an open question.
