Ga-PSMA PET/CT is a new imaging technique that is highly sensitive to metastatic prostate cancer lesions compared with other conventional imaging modalities. We report a case of a 77-year-old man with newly diagnosed prostate carcinoma who had a PSMA PET/CT scan for staging of his disease. An intensely PSMA-avid right pelvic mass was identified abutting the cecum and terminal ileum. Surgical removal and histopathologic examination of this lesion revealed the diagnosis of a desmoid tumor. It is important to be aware that many tumors other than prostate carcinoma may also show avid uptake on PSMA PET/CT scan.
镓-PSMA PET/CT 是一种新的成像技术，与其他常规成像方式相比，对转移性前列腺癌病变具有更高的敏感性。我们报告了一例 77 岁男性新诊断的前列腺癌患者，他进行 PSMA PET/CT 扫描以分期他的疾病。在 PSMA 上发现一个强烈摄取的右侧骨盆肿块，紧贴盲肠和末端回肠。对该病变进行手术切除和组织病理学检查，结果显示为硬纤维瘤的诊断。需要注意的是，许多除前列腺癌以外的肿瘤也可能在 PSMA PET/CT 扫描上显示摄取增加。
