Abstract：Objective: To investigate the 18F-FDG PET/CT features of metastatic renal tumors and in order to improve the acknowledge of the disease. Methods: From November 2013 to August 2019, 14 cases of renal metastases confirmed by surgical or puncture pathology were analyzed retrospectively. The maximum SUV of the lesions were obtained by drawing region of interest, and the size and CT value of the lesion were measured at the same time. Results: There were 18 lesions in 14 cases, including 5 cases of single lesion of left kidney, 6 cases of single lesion of right kidney, 2 cases of single lesion of double kidney, 1 case with 2 lesions in right kidney and 1 lesion in left kidney. There were 11 nodular increased uptake lesions, 6 annular high uptake lesions, and 1 arc-like high uptake focus. For all lesions, the Maximum SUVmax was 21.5, the Minimum SUVmax was 4.3, and with an average SUVmax was 11.6±5.5, there were 7 hypodensity foci, 8 isodensity foci and 3 hyperdensity foci, the boundary of all lesions was clear. The range of CT value was 15.0~35.0 HU, and the average CT value was (27.9±5.2)HU. Conclusion: Renal metastases show certain characteristics in 18F-FDG PET/CT imaging, and 18F-FDG PET/CT has a good diagnostic value for renal metastases.
