摘　　要：目的:探讨原发乳腺弥漫性大B细胞淋巴瘤的超声表现及临床价值。方法:回顾性分析7例经手术病理证实的原发乳腺弥漫性大B细胞淋巴瘤声像图特点、临床表现及病理结果。结果:7例患者共出现8个病灶,其中右乳6个病灶,左乳2个病灶。6例6个病灶最大径约3.5cm-6.2cm;1例双侧单发两个病灶,直径分别为2.3cm(右)、4.1cm(左)。3个病灶形态不规则、边界部分清楚、部分模糊;5个病灶类圆形、边界清楚。4个病灶外周部呈低回声、中央部呈高回声;3个病灶不均匀低回声,其内可见细网状、条索样回声;1个病灶为较均匀极低回声。7个病灶内部血流丰富,Adler血流分级II-III;其中3个病灶边缘见“贴边血管”征,4个病灶内部见“血管漂浮”征。1个病灶内部未见明显血流信号。6个病灶后方回声增强。8个病灶均无后方声影,周围组织结构均无扭曲改变。3例同侧腋窝淋巴结肿大。结论:原发乳腺弥漫性大B细胞淋巴瘤超声检查有一定的特征性表现,充分认识这些征象,有助于提高诊断准确率。Objective:To explore the manifestations and clinical value of ultrasound in primary breast diffuse large B-cell lymphoma.Methods:Retrospectively analyzed the sonographic characteristics,clinical manifestations and pathological results of 7 cases of primary diffuse large B-cell lymphoma confirmed by surgical pathology.Results:There were 8 lesions in 7 cases,6 lesions in the right breast and 2lesions in the left breast.The maximum diameter of 6 lesions in 6 cases was about 3.5cm~6.2cm;1 case had two single lesions on both sides,the diameters were 2.3cm(right)and 4.1cm(left).Three lesions were irregular in shape,partly clear and partly fuzzy;5 lesions were round with clear borders.4 lesions were hypoechoic in the periphery and hyperechoic in the central part;3 lesions were heterogeneously hypoechoic,and fine mesh and cord-like echoes could be seen inside;1 lesion was relatively uniform and extremely hypoechoic.The blood flow in 7 lesions was rich,and Adler's blood flow grade was II-III;"welt vessel"sign was seen on the edge of 3 lesions and"floating vessel"sign was seen inside 4 lesions.There was no obvious blood flow signal inside one lesion.There were 6 lesions with enhanced rear echoes.None of the8 lesions had a rear acoustic shadow,and no distortion of the surrounding tissue structure.3 cases of ipsilateral axillary lymph node enlargement.Conclusion:Ultrasound examination of primary DLBCL of the breast has certain characteristics,fully understanding these ultrasound signs can help improve the accuracy of diagnosis.
