目的 分析原发性非黏液瘤性良性心脏心包肿瘤的影像学特征 ,评估几种常用的影像学诊断方法的主要优势及局限性。资料与方法 搜集 1979年 1月～ 2 0 0 4年 3月间经手术及病理证实的原发性非黏液瘤性良性心脏心包肿瘤 4 4例 ,其中接受电子束CT(EBCT)检查者 2 0例 ,MRI检查者 16例。结果 X线平片示异常 31例 ;超声心动图 (UCG)定位诊断正确 31例 ;EBCT和MRI定位诊断全部正确 ,其中EBCT定性准确 9例 (脂肪瘤 4例 ,淋巴管瘤和心包囊肿各 2例 ,血管瘤 1例 ) ,MRI定性准确 9例 (脂肪瘤 5例 ,纤维瘤和囊肿各 2例 )。结论 X线胸片适合作为常规检查 ,UCG可作为首选初查且对心腔或心包腔内的肿瘤诊断准确率高 ,结合MRI高度的软组织分辨率和EBCT优良的空间、时间分辨率 ,可对大部分良性肿瘤进行组织学推断。
Objective To analyze the imaging features of primary non-myxomatous benign cardiac pericardial tumors and to evaluate the main advantages and limitations of several commonly used imaging diagnostic methods. Materials and Methods Forty four patients with primary non-myxomatous benign cardiac pericardial tumors confirmed by surgery and pathology from January 1979 to March 2004 were collected. Among them, electron beam computed tomography (EBCT) Cases, MRI examination in 16 cases. Results 31 cases were abnormal by X-ray and 31 cases by Echocardiography (UGG). All the correct EBCT and MRI were correctly diagnosed. EBCT was qualitative and accurate in 9 cases (4 cases of lipoma, 2 cases of lymphangioma and 2 cases of pericardial cysts 1 case of hemangioma), 9 cases of MRI (5 cases of lipoma, 2 cases of fibroma and cyst). Conclusion X-ray is suitable as a routine examination, UCG can be used as the first choice for the diagnosis of intracardiac or pericardial tumors with high accuracy, combined with MRI height of the soft tissue resolution and EBCT excellent spatial and temporal resolution, Most benign tumors were histologically inferred.
