CT and DSA images of a patient receiving 1 TACE treatment before combination therapy. a, b Axial CT showed a typical HCC enhancement pattern, including “wash in” in the arterial phase, “wash out” in the portal phase (white arrow) in the marginal zone, and necrotic foci in the centre. c, d DSA images before and after the initial TACE treatment; the tumour staining disappeared (white arrow). e Re-examination after one and a half months showed that the tumour had decreased in size and that viable tumours were present on the edges. f, g During the second TACE treatment, the tumour still showed staining (white arrow), indicating that the tumour blood vessels were recanalized and that the tumour was alive. The staining disappeared after treatment. h Re-examination after the combination therapy showed that the tumour had decreased in size and that there were no live foci. i, j Twelve months after late combination therapy, there was recurrence in the liver (red star sign)
