| 目的 观察睾丸原发癌及其转移癌18F-FDG PET/CT表现。方法 回顾性观察13例经病理证实的睾丸原发癌患者治疗前18F-FDG PET/CT资料,分析原发癌及其转移癌影像学特点。结果 共检出14个原发肿瘤,包括7例7个精原细胞瘤及6例7个非精原细胞肿瘤,平均最大径(3.44±1.75)cm;PET/CT均呈18F-FDG高摄取,中位最大标准摄取值(SUVmax)10.20(5.95,22.10),精原细胞瘤 与非精原细胞肿瘤 SUVmax差异无统计学意义 (Z=-0.96,P=0.338)。睾丸原发肿瘤SUVmax与其最大径、Ki-67指数均无明显相关(P均>0.05)。1例(1/13,7.69%)左侧精索受侵,SUVmax 8.80。13例中,11例(11/13,84.62%)存在淋巴结转移,以腹膜后淋巴结最常见,其次为纵隔及髂血管旁淋巴结转移,均表现为18F-FDG高摄取,平均SUVmax 15.65±7.97;8例(8/13,61.54%)发生血行转移,多表现为18F-FDG高摄取,以肺及肝脏受累最多,平均SUVmax分别为12.66±8.55和16.42±8.81。结论 睾丸原发癌均表现为18F-FDG摄取增高,可侵犯精索并转移至全身淋巴结、肺及肝脏等;转移癌亦多18F-FDG高摄取。 |

| Objective To observe 18F-FDG PET/CT manifestations of primary testicular cancer. Methods 18F-FDG PET/CT data of 13 patients with testicular cancer confirmed by pathology were reviewed, and the imaging findings were analyzed. Results A total of 14 primary testicular tumors were detected in 13 patients, including 7 seminomas in 7 cases and 7 nonseminomas in 6 cases, with the average maximum diameter of (3.44±1.75)cm, all with high uptake of 18F-FDG on PET/CT, and the media maximum standard uptake value (SUVmax) was 10.20 (5.95, 22.10). No significant difference of SUVmax was found between seminomas (9.10) and nonseminomas (12.20) (Z=-0.96, P=0.338). No obvious correlation was observed between SUVmax and the maximum diameter nor Ki-67 index of lesions (both P>0.05). One primary tumor (1/13, 7.69%) invaded the left spermatic cord with SUVmax of 8.80. Among 13 cases, 11 (11/13, 84.62%) accompanied by lymph node metastases, most commonly in the retroperitoneum, followed by the mediastinum and iliac vessels. All lymph node metastases showed high uptake of 18F-FDG, with an average SUVmax of 15.65±7.97. Blood metastases were detected in 8 cases (8/13, 61.54%), usually in the lungs and liver, with the average SUVmax of 12.66±8.55 and 16.42±8.81, respectively, most showed high uptake of 18F-FDG. Conclusion The primary lesions of testicular cancer had increased uptake of 18F-FDG, which could invade the spermatic cord and metastasize to lymph nodes, lungs and liver, most showed high uptake of 18F-FDG. |
