目的探讨肾癌胆囊转移瘤的CT表现,以提高对该病的认识和诊断水平。方法回顾性分析3例肾癌胆囊转移患者的临床和CT资料。结果所有病例均行腹部CT平扫和增强扫描,3例肾癌胆囊转移瘤均为单发,2例为实性,平扫为稍高密度,增强病灶明显强化;1例为囊实性,平扫为等低混杂密度,增强病灶呈环形明显强化;所有病灶均伴有胆囊外转移。结论肾癌胆囊转移瘤少见,常为单发病灶及胆囊外转移,CT主要表现为稍高密度、动脉期强化明显,病灶可有囊变坏死,结合原发病史可作出准确诊断。
Objective To investigate the CT manifestations of gallbladder metastases in renal cell carcinoma so as to improve their understanding and diagnosis of the disease. Methods Retrospective analysis of 3 cases of renal cell carcinoma of gallbladder metastasis of clinical and CT data. Results All patients underwent abdominal CT scan and enhanced scan. Three cases of renal cell carcinoma of the gallbladder metastatic tumors were single, 2 cases of solid, plain scan for a slightly higher density, enhanced lesions were significantly enhanced; 1 case of cystic solid, Flat scan for the other low-density, enhanced lesions was significantly enhanced ring; all lesions are associated with gallbladder metastasis. Conclusions There are seldom cases of metastatic renal cell carcinoma of gallbladder and often single lesion and extracranial gallbladder metastasis. The main manifestations of CT are slightly high density, obvious enhancement during arterial phase, cystic degeneration and necrosis of the lesion and accurate diagnosis based on primary history.
