【摘要】 目的探讨乳腺错构瘤的超声表现及其病理基础。方法回顾分析病理证实的23例乳腺错构瘤的超声图像与病理表现。结果所有病灶呈圆形或椭圆形,边界清楚,可见包膜,无后方回声衰减;内部回声因瘤体内所含脂肪和纤维腺体成分的数量不同而异,可分为3型:脂肪为主型、纤维(纤维腺体)为主型和脂肪纤维混合型。结论混杂回声及完整包膜是乳腺错构瘤的特征性表现。超声可清晰显示脂肪和纤维腺体成分分布的区域,切面形成特征性"香肠切片"样征象。更多还原

【Abstract】 Objective To investigate the sonographic characteristics and the pathological basis of the mammary hamartomas. Methods Pathological data and sonographic images of 23 breast hamartomas were retrospectively reviewed,and sonographic-pathologic correlation was elucidated. Results All the tumors were well circumscribed and surrounded by a true capsule,oval or round in shape,with no posterior acoustic shadowing. According to different amount of glandular fat and fibrous tissue in tumors,the internal echogenicity could be divided into three types:prominently fatty,prominently fibrous (fibroglandlar) and mixed fibrofatty. Conclusion Well-circumscribed and heterogeneous echogenicity are the typical findings of mammary hamartomas,and a characteristic "slice of sausage" appearance can be showed on ultrasounography.更多还原
