Spectrum of Unusual Imaging Findings of Metastatic Lesions from Gastric Cancer

Purpose: The purpose of this pictorial review was to present imaging findings of various unusual metastatic lesions from gastric cancer. Conclusion: Because of its tendency to cause the development of peritoneal implants, diffuse retroperitoneal tumor infiltration, and lymphangitic spread, poorly differentiated gastric adenocarcinoma can involve various organs and superficial regions. In addition, metastasis from alpha-fetoprotein (AFP)-producing gastric cancer may show giant lymph node metastasis, portal venous tumor thrombus, and hypervascular liver metastasis.
