Surgical Resection of a Solitary Metachronous Retrocaval Lymph Node Metastasis above the Renal Vein from Rectal Cancer.

ABSTRACT:

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).
