title: [Portosystemic shunt in a normal liver causing confusional states].
abstract: Portosystemic shunts are rare vascularization disorders, and an uncommon cause of confusional states. We report an 87-year-old male with a previously normal cognitive status who was repeatedly admitted for sudden symptoms of disorientation and functional limitation. The patient had high ammonium levels which lead to the suspicion of the presence a portosystemic shunt, even in the absence of pre-existing liver disease. A contrast enhanced computed tomography of the abdomen confirmed the presence an abnormal communication of the right portal vein with the suprahepatic veins. The communication was embolized and the confusional states of the patient subsided.
