摘　　要：目的描述罕见心脏肿瘤心脏嗜铬细胞瘤的二维心脏超声表现,探讨超声心动图的诊断价值。方法回顾性分析6例确诊的心脏嗜铬细胞瘤,重点分析其二维超声心动图特点,提出诊断注意点。结果5例患者心脏嗜铬细胞瘤在超声心动图上得到显示,其中1例有2个肿瘤。6个肿瘤分别位于左房后方降主动脉前方、主动脉根部前壁并突出于右室流出道、主动脉根部和左房后方间、主动脉根部右侧面、右侧房室沟、升主动脉和主肺动脉后方和左房顶部之间,不同程度与左房、周围大血管、右室流出道等结构紧密相连。4个肿瘤在非标准切面检出。肿瘤呈卵圆形,密度基本均匀。结论心脏嗜铬细胞瘤常位于心底部,紧邻主动脉根部等组织。对临床上疑诊嗜铬细胞瘤的患者应进行超声心动图检查以发现心脏嗜铬细胞瘤,尤其注意非标准切面的扫查。Objective To delinate the two-dimensional echo features of cardiac pheochromocytoma which was extremely rare and discuss the value of echo in diagnosing this disease. Methods The two-dimensional ultrasound features were analysed retrospectively in six patien＇~s with cardiac pheoehromocytoma confirmed pathologically and surgically. The important points of diagnosis were given. Results Among the six patients, five were found to have masses on ultrasound. There were two tumors in one patient while only one tumor existed in each of the other 4 patients. The six tumors located in between the posterior of left a＇~rium and anterior of descending aorta, in front of aortic root; in between the posterior of left atrium and aortic root; in right side of aortic root; in the right atrioventricular groove ; in between the ascending aorta pulmonary trunk and roof of left atrium, respectively. All the tumors were closely adjacent to the nearby structures. Four tumors were observed in non-standard section views. The tumors were characteristically round or ovoid with homogeneous echoes. Conclusions Cardiac pheochromocytomas often locate in the base of the heart, typically adjacent to or involving aorta and other structures. When pheochromocytoma is suspected clinically, echocardiography is advised to detect whether cardiac pheochromocytoma is present, especially non-standard echo views may be used.
