title: Hepatic encephalopathy secondary to transtumoral portal-hepatic venous shunting.
abstract: Intrahepatic portal-systemic shunts causing hepatic encephalopathy are very rare. This is a case report of a patient with hepatic metastases of a pancreatic islet cell tumor that manifested with transtumoral shunts leading to hepatic encephalopathy. The diagnosis was confirmed with Doppler ultrasound and initially treated with selective transhepatic portal vein embolization followed by hepatic artery embolization, and eventually radiofrequency ablation of the largest metastases. Despite excellent short-term palliation, symptom recurrence necessitated liver resection, the results of which proved durable. A multidisciplinary treatment plan for the identification and management of potentially salvageable encephalopathy in similar patients is described.
