When radiofrequency ablation was performed for the recurrent HCC 2 years ago, gastric cancer was incidentally found (fig. 1a). Additionally, multiple lung tumors were concurrently detected (fig. 1b).
MRI findings. a Contrast-enhanced T1-weighted image demonstrating a hyperintense tumor (arrow) with central necrosis. b T1-weighted FLAIR image showing a tumor with a hyperintense signal area, consistent with edema. The mass effect causes a midline shift (arrows).

Macroscopic examination of the resected specimen revealed that the tumor was yellowish-white, solid, and accompanied by necrosis (fig. 3a). Pathological examination revealed that the tumor was consistent with metastatic adenocarcinoma of gastric cancer origin (fig. 3b).
