1、医学影像学杂志2015年第25卷第6期JMedImagingVo1.25No.62015肺错构瘤CT征象分析及鉴别张兴强,李胜,葛鹏。(1.湖北省恩施土家族苗族自治州中心医院放射科湖北恩施445000;2.湖北医药学院附属人民医院放射科湖北十堰442000)【摘要】目的探讨肺错构瘤的CT征象特点,提高鉴别诊断能力。方法回顾性分析19例经手术病理确诊为肺错构瘤的CT图像,并分析各种征象的特点。结果19例肺错构瘤均为单发病灶,16例位于右肺(84.21),左肺3例(15。79%)。结节呈浅分叶17枚(89.47),呈圆形/类圆形改变15枚(88.24),边缘光整16枚(84.21),结节内
2、钙化18枚(94.74),其中爆米花样钙化1O枚(55.56),结节状钙化8枚(44.44);15枚可测得明显的脂肪密度(78.95)。1例结节邻近胸膜增厚(5.26),3例结节与肺门之间有粗细不均的索条影相连(15.79)。纵隔肺门淋巴结肿大并钙化1例(5.26%),CT增强显示肺动脉绕行结节,未见明显供血动脉。5例中4例轻度持续强化,1例中度强化。结论肺错构瘤CT表现具有较强的特征性,综合分析其CT特征有助于提高诊断符合率,减少误诊。【关键词】错构瘤;肺;体层摄影术,X线计算机;诊断中图分类号:R734.2:R814.42文献标识码:A文章编号:1006—9011(2O15)06—
