Although breast lesions are commonly detected because of their hypoechogenicity, some lesions may present with hyperechogenicity due to their histological components. Hyperechogenicity has been shown to be highly predictive of benignity; however, hyperechoic lesions can occasionally be malignant. This article reviews hyperechoic lesions of the breast, describes the underlying histological causes associated with hyperechogenicity, and the sonographic features useful for the differential diagnosis between benign and malignant hyperechoic lesions.
虽然由于其低回声性，乳腺病变通常被检测到，但由于其组织学成分，一些病变可能呈现出高回声。高回声已被证明对良性具有高度预测性；然而，高回声病变偶尔也可能是恶性的。本文回顾了乳腺的高回声病变，描述了与高回声相关的潜在组织学原因，以及有助于鉴别良性和恶性高回声病变的超声特征。
