292 Posterior reversible encephalopathy syndrome (pres) in a pregnant woman with an arachnoid cyst; Is there any connection?

Abstract

Posterior reversible encephalopathy syndrome (PRES)is an exceedingly rare disorder in pregnancy. It is associated with transient ischemic lesions in the “watershed” cortical areas of the posterior cerebral circulation in the parietal and occipital regions. Nowadays, although the underlying pathophysiological mechanism of PRES is still contentious, several risk factors such as hypertension, preeclampsia or eclampsia, and autoimmune disorders have been recognized. Herein, we describe a case of a previously healthy 17-years old primigravida woman at 34th week of pregnancy, which admitted to the obstetric ward of our hospital due to a premature rupture of membranes (PROM).
