A 79-year-old man was diagnosed with infrarenal abdominal aortic aneurysm extending to the right common iliac artery and rectal cancer. He underwent a Y graft replacement for abdominal aortic aneurysm and an anterior resection for rectal cancer after 1 month. No adjuvant therapy was performed. Eleven months after the operation to remove the rectal cancer, computed tomography examination revealed isolated para-aortic lymph node recurrence. The mass involved the right bundle branch of the synthetic graft and the right external and internal iliac artery. Therefore, we resected the area from the right bundle branch of the synthetic graft to the right external and internal iliac artery en bloc. Pathological examination of the resected specimen showed metastatic adenocarcinoma. No additional therapy was performed. As of 10 years after the second operation, the patient is alive and recurrence free. Isolated aortic lymph node recurrence may be cured by resection; hence, surgical resection should be considered if possible.
