Nonspecific uptake of prostate-specific membrane antigen (PSMA) on PSMA positron-emission tomography/computed tomography (CT) is normally encountered in benign conditions, which is detected on morphological changes on CT component. However, having a site of uptake without any CT finding is a rare occurrence. We herewith report one such rare case of a 66-year-old male with metastatic prostatic adenocarcinoma, who demonstrated an incidental finding of intense focal PSMA uptake in the lung parenchyma.
在前列腺特异性膜抗原（PSMA）正电子发射断层扫描/计算机断层扫描（CT）上，非特异性摄取PSMA通常见于良性情况，可通过CT部分的形态学改变检测到。然而，存在摄取部位但无任何CT表现的情况较为罕见。我们在此报告一例这样的罕见病例，一名66岁男性转移性前列腺腺癌患者，其肺实质内意外发现有强烈的局灶性PSMA摄取。
