Here we describe 2 cases of renal cell carcinoma where we found the unusual metastatic sites from renal cell carcinoma on 18F-FDG PET/CT scans in post-radical nephrectomy status. The first case resolves the venous migration of the tumor as a malignant thrombus arising from a remnant stump of the left renal vein, passing through hemiazygos vein further into the azygos vein and finally into the superior vena cava just before entering into the right atrium. The second case demonstrated extensive skeletal muscle deposits involving the muscles of the trunk as well as upper and lower extremities.
在这里我们描述了 2 例肾癌病例，我们在根治性肾切除术后的 18F-FDG PET/CT 扫描中发现了肾癌不常见的转移部位。第一个病例解决了肿瘤静脉迁移的问题，即肿瘤恶性血栓形成于左肾静脉残端，穿过半奇静脉进一步进入奇静脉，最终进入上腔静脉，就在进入右心房之前。第二个病例显示广泛的骨骼肌沉积，累及躯干以及上下肢的肌肉。
