Posterior reversible encephalopathy syndrome (PRES) in post liver transplantation

PRES (posterior reversible encephalopathy syndrome) is a neurological condition characterised by epileptic seizures, altered consciousness, visual disturbances and/or headache with typical neuroimaging showing reversible subcortical vasogenic oedema mainly in parieto-occipital regions. The pathophysiological mechanism is not fully understood. We present a clinical case in the field of liver transplantation where tacrolimus neurotoxicity may play a relevant role in the development of this syndrome.
