case_images: A 52-year-old man with liver metastasis and retroperitoneal lymph node metastases of renal cell carcinoma received drug-eluting bead transcatheter arterial chemoembolization. Preoperative CT enhanced scanning images of arterial phase (A, B). Intraoperative angiography showed apparent tumor staining (C, F) and lipiodol deposition after embolization (D, E).

case_images: The CT revealed multiple highly enhanced masses in the left renal region resembling enlarged retroperitoneal lymph nodes ( Figure 1A ) and a ring-enhanced mass with a 3.75 cm maximum diameter in segments VII and VIII of the liver ( Figure 1B ). The digital subtraction angiography indicated that the liver metastasis and retroperitoneal lymph node metastases were supplied by the right branch of the proper hepatic artery ( Figure 1C ) and the left inferior phrenic artery ( Figure 1F ), respectively. Then, he underwent drug-eluting bead transcatheter arterial chemoembolization (DEB-TACE) with two 50 mg doxorubicin-loaded callispheres of low diameter (70-150 mum) and TACE using a mixture of 2 mg raltitrexed and 7 ml lipiodol in each targeted artery ( Figures 1D, E ).
case_images: The enhanced MR images showed a complete response of the tumor after six months of follow-up. Axial and coronal MR images showed no tumor activity in both liver metastasis (A, C) and left retroperitoneal lymph node metastases (B, D).

case_images: After six months of follow-up, the enhanced MR scan showed no tumor activity in both liver metastasis ( Figures 2A, C ) and left retroperitoneal lymph node metastases ( Figures 2B, D ), indicating the complete response of this patient treated with DEB-TACE according to the Modified response evaluation criteria in solid tumors.
case_images: The enhanced CT scan showed no tumor activity in both liver metastasis (A) and left retroperitoneal lymph node metastases (B) after 15 months of follow-up. (C) The timeline with relevant events.
