Abstract

False positive findings in ¹⁸F-fluorodeoxyglucose positron emission tomography-computed tomography (¹⁸F-FDG PET/CT) scans can present challenges in the accurate diagnosis and staging of various conditions. We report a case of a 52-year-old male with known adenocarcinoma of the stomach who underwent total gastrectomy and chemotherapy and was referred for ¹⁸F-FDG PET/CT to rule out recurrence. ¹⁸F-FDG PET/CT showed a large FDG-avid lesion involving the entire right testicle mimicking testicular cancer or lymphoma. Further evaluation with ultrasonography revealed epididymo-orchitis, possibly of granulomatous etiology. Orchitis, an inflammatory condition of the testicles, can cause misleading results in ¹⁸F-FDG PET/CT imaging for cancer surveillance. Imagers should cautiously interpret PET/CT findings, considering clinical context, patient history, and additional imaging modalities to distinguish true malignancies from false positives.

炎性模拟：在[18F]-FDG PET/CT成像上伪装成恶性的附睾睾丸炎。

18f -氟脱氧葡萄糖正电子发射断层扫描-计算机断层扫描（18F-FDG PET/CT）的假阳性发现对各种疾病的准确诊断和分期提出了挑战。我们报告一例52岁的男性已知胃腺癌患者，他接受了全胃切除术和化疗，并被推荐进行18F-FDG PET/CT检查以排除复发。18F-FDG PET/CT显示大的fdg病变累及整个右睾丸，类似睾丸癌或淋巴瘤。进一步的超声检查显示附睾睾丸炎，可能是肉芽肿的病因。睾丸炎是睾丸的一种炎症，可导致用于癌症监测的18F-FDG PET/CT成像结果产生误导。成像人员应谨慎解释PET/CT的发现，考虑临床背景、患者病史和其他成像方式，以区分真正的恶性肿瘤和假阳性。
