Case 1. Hepatic metastasis from choriocarcinoma in a 33-year-old woman.. A. Arterial-phase celiac angiogram depicts multiple hypervascular masses with abnormal tumor vessels and saccular aneurysmal dilatation of the peripheral end of hepatic arteries in the liver and spleen.. B. Venous phase celiac angiogram demonstrates aneurysmal hepatic and splenic vascular lakes, but active bleeding is not apparent.

Diagnostic celiac angiography demonstrated multiple hypervascular masses with abnormal tumor vessels and saccular aneurysmal dilatation of the peripheral end of hepatic arteries at the arterial phase, and persistent visualization of hepatic and splenic vascular lakes at the venous phase, but active bleeding was not apparent (Figs. 1A, B).

Case 2. Hepatic metastasis from choriocarcinoma in a 33-year-old woman.. A. Contrast-enhanced CT image depicts huge, ill-defined, heterogeneously enhanced masses in both lobes of the liver, and thrombosis in the left portal vein.. B. Arterial-phase hepatic arteriogram reveals huge, multiple, exophytic hypervascular masses with saccular aneurysmal dilatation of the peripheral hepatic arteries and arteriovenous shunting in both lobes of the liver.. C. Venous-phase hepatic arteriogram demonstrates persistent hepatic vascular lakes.

Chest CT demonstrated that multiple hematogenous metastatic nodules extended throughout both lungs, while abdominal/pelvic CT revealed huge, ill-defined, heterogeneously enhanced masses in both lobes of the liver and thrombosis in the left portal vein (Fig. 2A). Active bleeding, was not apparent (Figs. 2B, C).
