Case Report

Introduction

Mediastinal lymph node metastasis occasionally occurs in patients with advanced gastric cancer of the cardia with esophageal invasion, but is rarely encountered in patients with gastric cancer at other sites [1]. Here we report an extremely rare case of occult hilar and mediastinal lymph node metastasis and malignant pleural effusion after distal gastrectomy for antral signet ring cell gastric cancer.

Case

A 66-year-old-male underwent right lower lobectomy and mediastinal lymph node dissection for squamous cell lung cancer. Five years previously, he had undergone laparoscopic distal gastrectomy for antral gastric cancer (pT2N2, pStage 3A, moderately differentiated adenocarcinoma-poorly differentiated signet ring cell carcinoma). Preoperative fluorodeoxyglucose (FDG)-positron emission tomography (PET) demonstrated an uptake of FDG (maximum standardized uptake value 6.3) in the pulmonary tumor, but no other significant uptake was evident (Fig.  1). Chest computed tomography...
