Radiotherapy for multiple brain metastases from hepatocellular carcinomas

Figure 1 Hepatic arteriography at the time of the third session of TACE shows arterial tumor vessels with arterioportal shunting.

Figure 2 Contrast-enhanced CT at the time of the diagnosis of brain metastases shows multiple hypervascular HCCs (arrows) (A, B, C). Lipiodol retention in the main tumor is seen (C).

Figure 3 Unenhanced T2-weighted MR images show hyperintense tumors in the cerebrum and cerebellum (arrows) (A, B, C, D). Contrast-enhanced T1-weighted MR images show ring-shaped enhancement of the tumors (E, F, G, H). On T2-weighted, unenhanced MR images, captured 3 mo after the completion of radiotherapy, the brain tumors have almost completely disappeared (I, J, K, L).
