【罕见同时侵犯左右心房的原发性心脏嗜铬细胞瘤】嗜铬细胞瘤是来源于神经嵴的产生儿茶酚胺的肿瘤。原发性心脏嗜铬细胞瘤是极为罕见的，全世界目前见于文献报道的仅为100例左右，北京协和医院心外科去年1月份成功进行了一例心脏嗜铬细胞瘤切除手术，患者为中年女性，肿瘤同时侵犯左右心房，其MIBG闪烁扫描的结果正常，但奥曲肽显像结果异常。肿瘤在体外循环下被成功切除。该病例报告已经发表在著名心胸外科专业杂志AnnalsofThoracicSurgery上。本文中的图表和表格Fig1.（A）99m-Technetium-labeledhydrazinonicotinyl-Tyr3-octretidescintiscandemonstratedafocusofintenseuptakeonrightsideofheartsilhouette.（B）Contrast-enhancedcomputedtomographicscanillustratedtumor（arrow）overlyinginteratrialgroove.（LA=leftatrium;RA=rightatrium.）[p=30,2,center]Fig2.Coronaryangiogramdemonstratedatumorblushwith2feedingvessels（whitearrows）branchingfromleftcircumflexartery.[p=30,2,center][img=360,387]http://w2.iiyi.com/bbs/uploadimg/z1357871845zakx8bt8.jpg[/img][p=30,2,center]Fig3.Resectedcardiacpheochromocytoma.PrimaryCardiacPheochromocytomaInvolvingBothRightandLeftAtriaXingrongLiu,MD,QiMiao,MD,HengZhang,MD,ChaojiZhang,MD,LihuaCao,MD,GuotaoMa,MD,ZhengpeiZeng,MDPheochromocytomasarecatecholamine-producingparagangliomasderivedfromtheneuralcrest.Primarycardiacpheochromocytomaisextremelyrare.Wedescribeacaseofcardiacpheochromocytomainvolvingbothrightandleftatriainamiddle-agedwoman.Metaiodobenzylguanidine（MIBG）scintiscanresultswerenormal,butresultsfromanoctreotidescanwereabnormal.Thetumorwassuccessfullyresectedusingcardiopulmonarybypass（CPB）。
