前列腺特异性膜抗原（PSMA）PET/CT已被证明在前列腺癌评估中具有有效性，并随着多种放射药物的商业化可用性而在临床中越来越常用。随着使用频率的增加，将遇到来自各种非肿瘤过程的偶发吸收，这将被视为解释性的困境。我们概述了一个71岁男性的个案，该个案接受了PSMA PET/CT成像，显示了左侧顶颞交界处的吸收，并证实为一种亚急性中风。该个案展示了PSMA PET上一种偶发吸收的报道原因，而其中的潜在机制尚不清楚。版权所有©2023 Wolters Kluwer Health, Inc. 保留所有权利。

Prostate-specific membrane antigen (PSMA) PET/CT has proven to be effective in the evaluation of prostate cancer and has become increasingly used clinically as multiple radiopharmaceuticals have become commercially available. With increasing use, incidental uptake from a variety of nononcologic processes will be encountered and considered interpretive pitfalls. We outline a case of a 71-year-old man who underwent imaging with PSMA PET/CT, which demonstrated uptake in the left parietal-temporal junction that was shown to be a subacute stroke. This case demonstrates a reported cause of uptake on PSMA PET for which the underlying mechanism is not yet well understood.Copyright © 2023 Wolters Kluwer Health, Inc. All rights reserved.
