29例心包转移瘤的CT诊断分析

CT diagnostic analysis on 29 cases of metastatic tumor of pericardium

目的探讨心包转移瘤的CT与临床表现特征。方法回顾性分析我院2014年1月-2015年8月收治并经临床证实的29例心包转移瘤CT与临床资料。结果 29例心包转移瘤中,原发灶为肺癌23例,恶性胸腺瘤2例,淋巴瘤2例,白血病1例,胰腺癌1例。CT上出现几率从高至低依次是心包积液（29例,100%）、心包淋巴结肿大（28例,97%）、心包增厚（24例,83%）、心包不规则增强（15例,52%）、心包结节（10例,34%）、心包直接侵犯（9例,31%）,为主要表现。CT上还可发现肺内原发或转移灶及纵隔、胸膜、骨质等的转移。CT随访可协助诊断及评价治疗效果。结论心包转移瘤原发灶以肺癌最为常见,CT及CT随访多可诊断心包转移瘤。

Objective To discuss the CT and clinical features of metastatic tumor of pericardium.Methods The CT and clinical material of 29 patients with confirmed metastatic tumor of pericardium treated in our hospital from January2014 to August 2015 were reviewed and analyzed.Results Among the 29 cases,the primary lesions of 23 cases were lung cancer,2 cases were malignant thymoma,2 cases were lymphoma,1 case was leukemia,and 1 case was pancreatic cancer.The occurrence probability in CT was successively hydropericardium（29 cases,100%）,pericardial lymphadenectasis（28 cases,97%）,pericardiac thickening（24 cases,83%）,pericardium irregular enhancement（15 cases,100%）.pericardium nodules（10 cases,34%）,pericardium direct invasion（9 cases,31%）.Lung primary or metastatic focus and metastasis on mediastinum,pleura and bones could also be observed in CT.CT follow-ups could facilitate diagnosis of disease and evaluation of treatment effect.Conclusion The most common primary focus of pericardium metastatic tumor is lung cancer.CT and CT follow-ups can facilitate the diagnosis of pericardium metastatic tumor.
