RATIONALE
Primary renal pelvis squamous cell carcinoma (SCC) is an extremely rare neoplasm. In many patients, the SCC was associated with renal calculi.
PATIENT CONCERNS
A 61-year-old male presented with intermittent pain at the left lumbar region for 3 days. The PET/CT images demonstrated increased F-FDG uptake in the upper pole of the left kidney and left renal hilar lymph nodes.
DIAGNOSES
Pathologic examination revealed well-moderately differentiated renal pelvis SCC with lymphatic metastasis.
INTERVENTIONS
The patient underwent a left nephrectomy a few days after the initial staging PET/CT study.
OUTCOMES
No growing lesion or metastasis was observed during a 6-month follow-up.
LESSONS
Our case demonstrates that F-FDG PET/CT is a useful diagnostic tool to evaluate primary renal pelvic SCC and detect metastatic lymph nodes in patients with long-standing calculi.
理论依据
原发性肾盂鳞状细胞癌（SCC）是一种极其罕见的肿瘤。在许多患者中，SCC与肾结石有关。
患者情况
一名61岁男性因左侧腰部间歇性疼痛3天前来就诊。PET/CT图像显示左肾上极和左肾门淋巴结的F-FDG摄取增加。
诊断
病理检查显示为中分化肾盂SCC伴淋巴转移。
干预措施
在初次分期PET/CT检查后几天，患者接受了左肾切除术。
结果
在6个月的随访期间未观察到病变进展或转移。
经验教训
我们的病例表明，F-FDG PET/CT是评估原发性肾盂SCC和检测长期患有结石患者转移性淋巴结的有用诊断工具。
