INTRODUCTION: Colorectal cancer (CRC) can metastasize to various sites, including the liver, lungs, ovaries, adrenal glands, and lymph nodes. Approximately 1%-2% of patients with CRC develop para-aortic lymph node metastases. Herein, we report a case of surgical resection of an isolated, metachronous, retrocaval lymph node recurrence of rectal cancer above the renal vein.
CASE PRESENTATION: A 77-year-old woman was diagnosed with a solitary metachronous retrocaval lymph node metastasis from rectal cancer. The patient underwent robot-assisted laparoscopic abdominoperineal resection. The pathological status was T3, N0, M0, or Stage IIA. No recurrence was observed for 13 months after the initial surgery. CT revealed a 24-mm tumor on the dorsal side of the inferior vena cava (IVC). Tumor resection was performed, including right adrenalectomy, Spiegel lobectomy, and partial resection of the IVC. Pathological findings revealed adenocarcinoma metastasis to a solitary lymph node, which invaded the IVC and Spiegel lobe.
CONCLUSIONS: This is the first report of a surgical resection of a retrocaval lymph node metastasis from CRC that invaded both the IVC wall and the liver.
