Posterior reversible encephalopathy syndrome following an inadvertent dural puncture during an emergency laparotomy for ischemic colitis - a case report.

Posterior reversible encephalopathy syndrome (PRES) is a clinico-neuroradiological syndrome characterized by various symptoms of neurological disease. It has commonly been reported in association with acute hypertension, pre-eclampsia, eclampsia, sepsis, and exposure to immunosuppressants. Here, we report on a normotensive woman who developed a severe frontal headache, visual disturbances, and hypertension 3 days after undergoing an emergency laparotomy for ischemic colitis during which she suffered an inadvertent dural puncture.
