Abstract

A 74-year-old man with suspected prostate cancer and a previously negative transrectal ultrasound-guided prostate biopsy underwent Ga-PSMA PET/CT. Scan showed no abnormal tracer concentration in enlarged prostate gland to suggest prostate cancer. Note was made of an incidentally detected well defined soft tissue lesion in the greater curvature of the stomach with moderate tracer concentration in its intraluminal portion. Biopsy of the lesion revealed gastrointestinal stromal tumor.

摘要

一位 74 岁男性，疑诊前列腺癌，此前经直肠超声引导前列腺活检阴性，行 Ga-PSMA PET/CT 检查。扫描显示前列腺增大，未见异常示踪剂浓聚，提示前列腺癌。偶然发现胃大弯处有一个边界清楚的软组织病变，腔内部分有中度示踪剂浓聚。病变活检显示胃肠道间质瘤。
