非哺乳期慢性乳腺炎的超声特征与BI-RADS分类

目的：探讨非哺乳期慢性乳腺炎的超声声像图特征,为临床治疗方案的选择提供依据.方法：对46例患者进行彩超检查,了解肿块的形态、回声、大小、边界、有否钙化及血流情况,分析其超声声像图特征并予BI-RADS分类.结果：46例病例中病理结果显示慢性化脓性乳腺炎20例,慢性肉芽肿性乳腺炎19例,浆细胞性乳腺炎7例.慢性化脓性乳腺炎超声图像有大片液性回声区为其特征性表现;肉芽肿性乳腺炎回声紊乱,偶见少量液性区;浆细胞性乳腺炎无特征性表现.BI-RADS分类为3类31例,4类13例,其中4C类4例.结论：综合分析乳腺肿块高频超声特征,结合病史及体征,是提高非哺乳期慢性乳腺炎诊断率的有效方法.

Ultrasonographic features of non-lactation chronic mastitis and BI-RADS category

Objective： To study the sonogram characteristics of non-lactation chronic mastitis, provide the diagnosis proof for clinic. Methods： All the 46 cases were examined by ultrasound. The position, shape, internal echo, capsule, calcification and blood flow of the masses were observed. A retrospective analysis was performed. Results： Twenty cases were chronic suppurative mastitis, 19 cases were granulomatous mastitis, 7 cases were plasma cell mastitis. All were comfirmed by patholo- gy. Chronic suppurative mastitis ultrasound images with large liquid echo area were its characteristics. Granulomatous mastitis images were echo disorders, occasionally small amounts of liquid zone. Plasma cell mastitis images were without features. In 46 patients, 31 were BI-RADS category 3, 13 were category 4, 4 were category 4C. Conclusion： By analyzing the sonogram characteristics of mammary lump, combination with clinical characteristics could improve the accuracy rate of diagnosis.
