BACKGROUND
An 81-year-old man presented with a history of right nephrectomy for renal cell carcinoma, chronic renal insufficiency and implanted defibrillator. He was asymptomatic. Contrast-enhanced CT and MRI were contraindicated.
INVESTIGATIONS
Non-contrast CT, positron emission tomography (PET), fused PET-CT and Doppler ultrasound.
DIAGNOSIS
Small exophytic left midpole renal tumor, 3.7 cm in size.
MANAGEMENT
Percutaneous CT-guided renal cryoablation, followed up with PET-CT imaging.
背景
一名81岁男性，有因肾细胞癌行右肾切除术、慢性肾功能不全及植入式除颤器病史。他无症状。禁忌行增强CT和MRI检查。
检查
非增强CT、正电子发射断层扫描（PET）、PET-CT融合成像及多普勒超声检查。
诊断
左肾中极外生性小肿瘤，大小为3.7厘米。
治疗
在CT引导下经皮肾冷冻消融术，之后行PET-CT成像随访。
