Gastric metastasis from renal cell carcinoma with a 10-year interval: A case report

Figure 2 Recurrent and metastatic lesions in the lungs, left renal pelvis, and retroperitoneal soft tissues were identified via positron emission tomography/computed tomography in December 2022. A: Hyperdense nodule with slightly increased 18F-fluorodeoxyglucose (18F-FDG) uptake in the left renal pelvis; B: Soft tissue mass with increased 18F-FDG uptake in the space between the upper pole of the left kidney and the posterior aspect of the pancreatic tail; C: Round solid nodule with slightly increased 18F-FDG uptake was detected in the left lung, suggestive of pulmonary metastatic tumors.
