摘要：
我们报告了一位68岁的男性患者，被诊断为新近发现的高危前列腺癌，由于初始CT显示左腹股沟管内出现类似淋巴结的增强结构，被转诊接受PSMA PET/CT检查。在CT或骨扫描中未见其他提示转移性疾病的发现。PSMA PET/CT显示在腹股沟组织中有中度的PSMA摄取，证实了淋巴结转移的意外部位。这一罕见的部位需要进行切除活检，组织学检查诊断为静脉注射性肉芽肿，强调了对意外发现进行活检的重要性。(c) 2023 Wolters Kluwer Health, Inc. 版权所有。
We present a 68-year-old man with newly diagnosed high-risk prostate cancer who was referred for PSMA PET/CT after the initial CT showed a contrast-enhanced structure resembling a lymph node in the left inguinal canal. No other findings suggesting metastatic disease were seen on CT or bone scintigraphy. PSMA PET/CT showed moderate PSMA uptake in the inguinal tissue, substantiating an unexpected location of lymph node metastasis. The uncommon location warranted an excision biopsy, and an IV pyogenic granuloma was diagnosed on histological examination, emphasizing the importance of biopsy of unexpected findings.Copyright © 2023 Wolters Kluwer Health, Inc.
