摘要
目的评价超声检查在诊断导管内乳头状瘤的应用价值。方法对70例91个超声诊断为导管内乳头状瘤进行病理检查,计算其阳性预测值,并对导管内乳头状瘤声像图特点包括二维、彩色多普勒、频谱多普勒、弹性成像特点进行归纳分析。结果 50例71个病灶病理检查证实为导管内乳头状瘤,阳性预测值78.26%。二维声像图表现多为中央型(94.37%),单病灶多见(82%),形态包括导管内结节、囊性结构内乳头状凸起、囊实混合性及实性结节,回声为低到中等,边界清晰,无明显钙化。彩色多普勒血流显像定量显示以2级以上血流为主(60.56%)。频谱多普勒显示峰值血流速度(11.41±6.41)cm/s,阻力指数(0.68±0.06)。弹性成像主要为1～3级(94.37%)。结论导管内乳头状瘤声像图有特异性表现,超声检查可作为诊断导管内乳头状瘤的首选检查方法。
Objective To investigate the value of ultrasound in the diagnosis of intraductal papilloma.Methods Pathological examination was performed to 91 nodules in 70 cases that had been diagnosed as intraductal papilloma by ultrasound and the positive predictive value was calculated.And the features of 2-dimentional sonography,color Doppler flow imaging,spectral Doppler imaging and elastography of intraduactal papilloma were analyzed.Results Seventyone intraductal papillomas of 50 cases were confirmed by pathological examination,the positive predictive value of which was 78.26 %.The sonography showed that the lesions were mainly single and of center type,with a diversity of morphology,CDFI showed blood flow of above 2 degree,and elastography presented the elasticity of 1~3 degree.Conlusion There are special features in the ultrasonography of intraductal papilloma,so ultrasound can be its first choice examination method.
