Ga-prostate-specific membrane antigen (PSMA) PET/CT is a rapidly evolving diagnostic technique to image prostate cancer. In contrast to the name PSMA, various tissues show Ga-PSMA uptake in PET/CT imaging. We present a case of a 68-year-old man with prostate cancer who underwent Ga-PSMA PET/CT. Along with metastatic lymph nodes, multiple nodular lesions within the peritoneal spaces of all 4 quadrants of the abdomen showed high PSMA expression. Because of a history of splenic rupture, a Tc-labeled heat-denatured erythrocyte scintigraphy and SPECT were performed. Peritoneal lesions showed high uptake, confirming widespread peritoneal splenosis.
前列腺特异性膜抗原（PSMA）Ga-PET/CT 是一种用于前列腺癌成像的快速发展的诊断技术。与 PSMA 的名称不同，各种组织在 PET/CT 成像中都显示出 Ga-PSMA 的摄取。我们报告了一例 68 岁患有前列腺癌的男性患者，他接受了 Ga-PSMA PET/CT 检查。除了转移性淋巴结外，腹部 4 个象限的腹膜腔内的多个结节性病变也显示出 PSMA 高表达。由于脾破裂的病史，进行了 Tc 标记的热变性红细胞闪烁显像和 SPECT。腹膜病变显示出高摄取，证实了广泛的腹膜脾种植。
