摘要
目的探讨原发性肾鳞状细胞癌的CT表现及其诊断和鉴别诊断。方法回顾性分析2009年3月至2020年5月在焦作市人民医院收治的6例经病理证实的原发性肾鳞状细胞癌患者的影像学和临床资料。结果男性5例,女性1例,均单发,肿瘤最大径>5cm。CT平扫肿瘤位于肾实质内,2例呈实性,4例囊实性,3例并肾结石及不同程度积水。增强扫描病灶呈轻到中等度不均匀强化,与周围肾实质分界不清,4例同侧腰大肌受侵并1例相邻肋骨骨质破坏,5例腹膜后淋巴结转移。结论原发性肾脏鳞状细胞癌罕见,长期肾结石、肾积水患者并出现边界不清,轻、中度强化的实性占位时,应考虑本病的可能。
Objective To investigate the CT manifestations of primary renal squamous cell carcinoma,and to discuss its diagnosis and differential diagnosis.Methods The imaging materials and the clinical data of 6 patients with primary renal squamous cell carcinoma were retrospectively analyzed.Results There were 5 males and 1 female,all with a single tumor with a maximum diameter of>5 cm.The tumor was located in the renal parenchyma on plain CT scan,2 cases were solid,4 cases were cystic-solid,3 cases were complicated with kidney stones and different degrees of hydronephrosis.On contrast-enhanced scan,the lesions showed slight to moderate non-uniform enhancement with ill-defined margin,ipsilateral psoas major muscle invasion in 4 cases and bone destruction of adjacent rib in 1 case,retroperitoneal lymph node metastasis in 5 cases.Conclusion Primary squamous cell carcinoma was rare,when patients with long-term renal calculi and hydronephrosis appear solid mass with unclear boundaries and mild to moderate enhancement,is highly suggestive of primary squamous cell carcinoma.
