Core Tip
Core Tip: Posterior reversible encephalopathy syndrome (PRES) is a clinicoradiological syndrome characterized by predominant parietal and occipital involvement, which can be reversible within a few days. We report a rare case of PRES that developed after clipping surgery for an unruptured intracranial aneurysm (UIA). In our case, the important causative factor of PRES was suspected to be a sudden increase in cerebral perfusion pressure associated with temporary M1 occlusion. Our unique case highlights that, to our knowledge, this is the second report of PRES developing after craniotomy for the treatment of UIA. Surgeons must keep PRES in mind as one of the causes of perioperative neurological abnormality following clipping of an UIA.
