Objective: To assess the clinical presentation and neuroimaging abnormalities in a series of patients diagnosed as posterior reversible encephalopathy syndrome at Military Hospital Rawalpindi.                                                                                                                                                          Study Design: Case series study.                                                                                                                                                                                                              Place and Duration: Study was carried out at Military Hospital Rawalpindi from December 01st , 2011 to May 31st, 2012.                                        Patients and Methods: Study included all the cases of the Posterior reversible encephalopathy syndrome (PRES) admitted in the wards and intensive care unit (ITC). Neuroimaging was done and all the studies were reviewed by independent neuroradiologist. Different clinical and laboratory variables were also studied and correlated with neuroimaging. Follow up was done to look for the prognosis.                                                          Results: Of the seven patients labelled as PRES two were male and five were female. Two patients were over 50 years of age, out of them one was male and one was female. One patient had end stage renal disease (ESRD) secondary to diabetes mellitus (DM) and hypertension (HTN), one had eclampsia, one had pregnancy-induced hypertension (PIH) and one had just uncontrolled HTN. Peak spontaneous bacterial peritonitis (SBP) in 5 cases was 210 mm of Hg, four of which had seizures. Rest two had spontaneous bacterial peritonitis (SBP) of 160 out of which one developed seizures. Total out of 7, 5 experienced seizures and altered conscious state, rest two only had confusion. One patient had papilloedema. Follow up was done after 06 weeks, 02 patients died, 05 remained alive and symptoms of PRES had vanished.                                                                              Conclusion: PRES is a neurological emergency, presents with a variety of symptoms and has a specific neuroimaging pattern. Early recognition and prompt treatment result in a good neurological outcome.
