目的：回顾分析罕见的原发性非粘液性心脏肿瘤（PNCT）的临床、病理及超声心动图特点，探讨超声心动图对良、恶性PNCT及各种病理分型的诊断特点。方法：对2003-01至2013-02在我院住院确诊的32例PNCT患者（包括良性肿瘤组21例和恶性肿瘤组11例）的超声心动图、计算机断层摄影术（CT）或磁共振成像（MRI）、手术、病理资料做回顾性分析。本组32例PNCT患者中，男23例，女9例，年龄为0.5~66岁，平均年龄（36.92±20.17）岁；均为病理结果证实。结果：通过统计学分析发现：良性肿瘤组（男/女：16/5）和恶性肿瘤组(男/女：7/4)中男性均高于女性（P<0.05），差异有统计学意义；良性肿瘤组年龄[(38.06±21.68)岁]与恶性肿瘤组[（35.72±13.55）岁]比较差异无统计学意义（P>0.05）。从婴儿至成人均可出现该疾病。在肿瘤发生位置上，良性肿瘤组左侧心腔内发生率高，恶性肿瘤组主要发生在右侧心腔内；与良性肿瘤组相比，恶性肿瘤组患者多表现为肿瘤无蒂、形态不规则、心包积液和多有周围组织受累。结论：超声心动图是诊断PNCT的敏感方法，能够初步鉴别良性、恶性PNCT。各种病理分型的PNCT超声心动图声像图特征有所不同。%Objective: To explore the clinical, pathological and echocardiographic characteristics of rare primary non-mucinous cardiac tumor (PNCT) and to investigate the diagnostic value of echocardiography in benign and malignant PNCT with various pathological classiifcations. Methods: We retrospectively studied 32 PNCT patients including 21 benign and 11 malignant patients treated in our hospital from 2003-01 to 2013-02. There were 23 male and 9 female from 0.5 to 66 (36.92 ± 20.17) years of age. We analyzed the clinical information of echocardiography, CT, MRI and operation, and the ifndings were conifrmed by pathology. Results: Statistic analysis presented that there were more male PNCT patients than female, the ratio of male/female in benign patients was 16/5, in malignant patients was 7/4, P<0.05, the age was similar between 2 groups, (38.06 ± 21.68) years vs (35.72 ± 13.55) years,P>0.05, and either infant or adult could suffer from PNCT. Benign PNCT was more in left heart and malignant PNCT was more in right heart. Compared with benign PNCT, malignant lesions were usually no base, with irregular shape, pericardial effusion and surrounding tissue adhesion. Conclusion: Echocardiography was sensitive for diagnosing the patients with PNCT, it could preliminarily identify benign and malignant lesions with different ultrasonographic manifestation.
