[Portosystemic shunt encephalopathy. Clinical and radiological evaluation by using multidetector-row CT angiography]. / Encefalopatia da shunt portosistemico. Valutazione clinica e radiologica con angio-TC multidetettore.

ABSTRACT

We describe the case of a 72-year-old woman who presented a symptomatology characterized by recurrent episodes of confusion, weakness with cerebral vasculopathy. The high values of ammonium were correctly defined thanks to the diagnostic multidetector-row CT information and we referred the symptoms to porto-systemic shunts with the exclusion of hepatic vascularization due to an inferior vena cava stenosis.
