A 58-year-old man with large penile wound and enlarged regional lymph node was suspected of having disseminated penile cancer. FDG PET/CT for primary staging showed high FDG uptake on penis and in several enlarged lymph nodes. However, biopsies revealed no signs of malignancy, but ulceration, inflammation, fibrosis, and spirochetes. Furthermore, Wassermann test was positive. The patient was then treated for syphilis. To our knowledge, this is the first report on FDG PET/CT in a patient suspected of having penile cancer that turned out to be syphilis. Thus, syphilis can be added to the list of benign pitfalls in FDG PET/CT.
一位 58 岁男性,阴茎有大伤口且局部淋巴结肿大,疑似患有阴茎癌。为进行初步分期,对其进行了 FDG PET/CT 检查,结果显示阴茎和数个肿大的淋巴结摄取了大量 FDG。然而,活检未发现恶性肿瘤的迹象,仅显示溃疡、炎症、纤维化和螺旋体。此外,瓦氏试验阳性。随后,该患者接受了梅毒治疗。据我们所知,这是首例疑似患有阴茎癌但最终诊断为梅毒的患者的 FDG PET/CT 报告。因此,梅毒可被列入 FDG PET/CT 中的良性陷阱列表中。
