原发性尿道尿路上皮癌是一种罕见的侵袭性肿瘤，具有高度局部侵袭和区域及远端转移的倾向。我们描述了 FDG PET/CT 在治疗原发性尿道尿路上皮癌患者中的有用性。 FDG PET/CT 初步分期显示 FDG 阳性的原发肿瘤和左侧腹股沟的淋巴结转移，肺转移瘤由于体积小而有轻度或无活动性。 4 个周期化疗后 FDG PET/CT 显示原发肿瘤和肺转移进展，左侧腹股沟淋巴结肿大部分缓解，以及多个新位点 FDG 亲和性转移。版权所有 © 2024 Wolters Kluwer Health, Inc. 保留所有权利。

Primary urethral urothelial carcinoma is a rare aggressive tumor with a high propensity for local invasion and regional and distal metastases. We describe the usefulness of FDG PET/CT in management of a patient with primary urethral urothelial carcinoma. FDG PET/CT at initial staging showed FDG-avid primary tumor and lymph node metastasis of the left groin, and mild or no activity of the lung metastases due to small size. FDG PET/CT after 4 cycles of chemotherapy showed progression of the primary tumor and lung metastases, partial response of the left inguinal lymphadenopathy, and multiple new sites of FDG-avid metastases.Copyright © 2024 Wolters Kluwer Health, Inc.
