Metastatic tumors of the penis are rare, with priapism as the predominant symptom in a significant number of cases. The genitourinary tract and rectum are the most common primary sites. FDG PET/CT has established role in detection of distant metastasis in various malignancies. The authors describe a case of mucoid adenocarcinoma of cecum, presented with priapism after right hemicolectomy, where FDG PET/CT showed intense tracer uptake throughout the enlarged penis, which was later confirmed as metastatic adenocarcinoma by trucut biopsy.
阴茎转移瘤较为罕见，有相当数量的病例以阴茎异常勃起为主要症状。泌尿生殖系统和直肠是最常见的原发部位。FDG PET/CT 在各种恶性肿瘤远处转移的检测中具有重要作用。作者描述了 1 例右半结肠切除术后以阴茎异常勃起为表现的盲肠黏液腺癌，FDG PET/CT 显示整个增大的阴茎摄取了大量示踪剂，随后经 tru-cut 活检证实为转移性腺癌。
