ABSTRACT
Transarterial chemoembolization of hepatocellular carcinoma consists of the selective release of chemotherapeutic agents in the tumor feeding arteries (and their subsequent occlusion) and presents a low risk of extrahepatic complications. However, the presence of anatomical variants of the celiac trunk is common and facilitates these complications by connecting the hepatic arterial vascularization with that of the surrounding organs. We present three clinical cases of extrahepatic ischemia in three different organs (esophagus, stomach and gallbladder) following transarterial chemoembolization in patients who presented one of these anatomical variants.

Hepatic hemangioendothelioma is a rare tumor which has malignant potential and a difficult radiological differential diagnosis that includes many others liver tumors as metastasic carcinoma, cholangiocarcinoma and, especially, angiosarcoma. Thus, it is an entity that is usually not diagnosed in an accurate way by radiology and further histolopathological study is needed. However, hemangioendothelioma can present certain specificied patterns in contrast-enhanced imaging. In this regard, we present the case of a patient with an epithelioid hemangioendothelioma that shows these radiological features.
