Lymphoma is a rare malignancy of the breast, comprising approximately 0.04 to 0.5% of breast malignancies. Because the clinical findings of breast lymphoma are nonspecific and similar to those of breast carcinoma, it is important to distinguish breast lymphoma from other breast disease on the basis of radiologic findings. Elastography is an interesting imaging tool that reflects the tissue stiffness, increasingly being used in the evaluation of breast tumours. However, only a limited number of studies have focused on the elastographic findings of breast lymphoma. In this report, we review the radiologic characteristics of primary breast lymphoma including elastographic feature. A 57-year-old woman presented with a painless palpable mass of the left breast. Ultrasonography revealed an irregular-shaped complex cystic and solid mass with increased vascularity in upper outer breast. On shear wave elastography, the mass was relatively stiff with maximum elasticity value (E) of 100.5 kilopascal (kPa). The mass was confirmed as diffuse large B-cell lymphoma by US-guided core needle biopsy.
淋巴瘤是一种罕见的乳腺恶性肿瘤，约占乳腺恶性肿瘤的0.04%至0.5%。由于乳腺淋巴瘤的临床表现不具有特异性，与乳腺癌相似，因此根据影像学表现将乳腺淋巴瘤与其他乳腺疾病区分开来很重要。弹性成像作为一种反映组织硬度的有趣成像工具，越来越多地用于乳腺肿瘤的评估。然而，仅有有限数量的研究关注乳腺淋巴瘤的弹性成像表现。在本报告中，我们回顾了原发性乳腺淋巴瘤的放射学特征，包括弹性成像特征。一名57岁女性因左侧乳腺可触及无痛性肿块就诊。超声检查显示乳腺外上象限有一个不规则形的复杂囊实性肿块，血管增多。剪切波弹性成像显示该肿块相对较硬，最大弹性值（E）为100.5千帕（kPa）。经超声引导下的粗针穿刺活检，该肿块被确诊为弥漫性大B细胞淋巴瘤。
