Breast ultrasound is helpful in the characterization of masses to differentiate benign from malignant disease. The internal echotexture of a mass is an important ultra-sound feature in breast diagnostic workup. This article reviews the imaging and histopathology findings of benign and malignant hyperechoic masses to better recognize these conditions.
Hyperechoic masses are frequently benign, including hematoma, fat necrosis, abscess, and benign neoplasm. Malignant hyperechoic lesions include invasive ductal and invasive lobular carcinoma, lymphoma, and sarcoma. Understanding lesion echotexture in the context of clinical and mammographic findings will help establish appropriate diagnoses for hyperechoic masses.
乳腺超声有助于对肿块进行特征描述,以区分良性和恶性疾病。肿块的内部回声质地是乳腺诊断中一个重要的超声特征。本文回顾了良性和恶性高回声肿块的影像学和组织病理学表现,以更好地识别这些病变。
高回声肿块通常为良性,包括血肿、脂肪坏死、脓肿和良性肿瘤。恶性高回声病变包括浸润性导管癌和浸润性小叶癌、淋巴瘤和肉瘤。了解病变回声质地在临床和乳腺 X 线摄影表现下的特征有助于对高回声肿块做出恰当的诊断。
