We present a case of a diverticulum of the sigmoid colon with intense prostate-specific membrane antigen (PSMA) activity on Ga-PSMA PET/CT. CT scan and colonoscopy showed no signs of inflammation or malignancy. This case presents an addition to the collection of benign pitfalls when reporting PSMA PET/CT; however, a Ga-PSMA up-taking focus in the colon should always cause further examination, as malignant etiology must be ruled out.
我们报告了一例乙状结肠憩室，在 Ga-PSMA PET/CT 上表现出强烈的前列腺特异性膜抗原（PSMA）活性。CT 扫描和结肠镜检查均未显示炎症或恶性征象。本病例为报告 PSMA PET/CT 时良性陷阱的又一补充；然而，结肠中出现 Ga-PSMA 摄取灶时应始终进行进一步检查，因为必须排除恶性病因。
