We report a case of 58-year-old woman referred to our service for an (18)FFDG PET/CT study of initial staging after being diagnosed of a pelvic kidney mass consistent with malignancy. The FDG-PET showed an abnormal mass in the right kidney, a suspicious metastasis versus a second primary tumor in the cortex of the kidney and lymph node infiltration in the paracaval nodes. The histological analysis verification after exeresis of the lesions confirmed the diagnosis of renal metastases. In this article, we present a brief review of the literature published on the role of PET in the characterization and initial staging of kidney and urinary tract tumors. We also stress the clinical importance of carefully evaluating any low attenuation lesion or focal glucose uptake detected in these structures in a PET/CT study with (18)FFDG.
我们报告了一例58岁女性，在被诊断为盆腔肾肿块且疑似恶性肿瘤后，转诊至我院进行（18）氟代脱氧葡萄糖正电子发射断层显像/计算机断层扫描（FFDG PET/CT）初始分期检查。FDG-PET显示右肾有一异常肿块，肾皮质有一处可疑转移灶或第二原发性肿瘤，腔静脉旁淋巴结有浸润。病变切除后的组织学分析证实为肾转移瘤。在本文中，我们简要回顾了关于PET在肾脏和尿路肿瘤的特征描述及初始分期中作用的文献。我们还强调了在（18）FFDG PET/CT检查中仔细评估这些结构中检测到的任何低密度病变或局灶性葡萄糖摄取的临床重要性。
