【摘要】 目的：旨在探寻嗜铬细胞瘤（ＰＨＥＯ）声像图规律，为临床诊治提供可靠依据。方法：观察整理了６６例－８４枚ＰＨＥＯ的声像图。结果：４２例肾上腺ＰＨＥＯ中５例为恶性，２３例肾上腺外ＰＨＥＯ中８例为恶性。经统计学处理肾上腺内外恶性ＰＨＥＯ发生率的差异性（Ｇ＝４．７５，Ｐ＝０．０３）有意义。肿瘤最大径１～１８ｃｍ，瘤体重３～１７００ｇ。声像图表现：实质性肿瘤４４枚占５２．３８％（４４／８４），混合性３９枚占４６．４３％（３９／８４），囊性１枚占１．１９％（１／８４）。根据瘤体形态是否规则，包膜是否完整以及边界是否清晰与恶性ＰＨＥＯ发生率的关系，作统计学处理（Ｇ＝２６．２，Ｐ＜０．００１）有显著差异。结论：ＰＨＥＯ声像图尽管有某些特异性，但更重要的是声像图的广泛性更多还原

【Abstract】 Purpose:To find out some reliable evidences on the sonograms of pheochromocytoma(PHEO)to clinch clinical diagnosis.Method:66 PHEO patients 84 sonograms were studied.Results:5 cases were malignant in 42 cases of adrenal PHEO,8 cases were malignant in 23 cases of extra adrenal PHEO.The malignant PHEOs occurrence rates between adrenal and extra adrenal had significant difference(G=4 67,P=0 03).The PHEOs size varied from 1 to 18cm and weight varied from 3 to 1700gm.The noted sonographic appearances included 44 solid masses (52 38%),39 complex masses(46 43%),and 1 cystic mass(1 19%).there was significant difference of the malignant PHEOs occurrent rate(G=26 2,P<0 001),most related to the regularities of the PHEOs capsule and boundary.Conclusion:Even though the PHEOs sonograms possess certain specificity,its broad diagnostic spectra should be scrutinized.更多还原
