Abstract：
We present the case of a 75-year-old female in which a pulmonary tumor embolism was detected incidentally on a prostate-specific membrane antigen positron emission tomography-computed tomography restaging scan. This occurred on the background of renal cell carcinoma in remission with pazopanib systemic therapy and a right nephrectomy 4 years prior. An avidity to prostate-specific membrane antigen in the superior lingula of the left upper lobe of the lung coupled with contrast-enhanced computed tomography findings found the lesion to be a tumor thrombus. This case serves to highlight the effectiveness of incorporating contrast-enhanced computed tomography with prostate-specific membrane antigen positron emission tomography and to consider the rare diagnosis of a pulmonary tumor embolism.
摘要：
我们介绍了一名75岁女性的病例，其中在前列腺特异性膜抗原正电子发射断层扫描-计算机断层扫描重新扫描中偶然发现了肺肿瘤栓塞。这是在4年前通过帕唑帕尼全身治疗和右肾切除术缓解肾细胞癌的背景下发生的。肺左上叶上舌部对前列腺特异性膜抗原的亲和力加上对比增强的计算机断层扫描发现，该病变是肿瘤血栓。此病例突出了将对比增强计算机断层扫描与前列腺特异性膜抗原正电子发射断层扫描相结合的有效性，并考虑了对肺肿瘤栓塞的罕见诊断。
