| 目的:观察不同生理阶段乳腺乳汁淤积囊肿的超声声像图特点，提高乳汁淤积囊肿的超声诊断水平。方法:回顾性分析56例乳汁淤积囊肿患者的超声声像图资料，总结其声像图特征，比较乳腺不同生理阶段乳汁淤积囊肿的声像图表现。结果:哺乳期导管扩张较广泛，单纯乳汁潴留时扩大的导管内有浮动微细亮点，大片液性暗区有纤维间隔呈多房状；继发感染时脓腔可破溃,脓汁溢出。哺乳期后扩张乳管呈液性无回声或低回声，与滞留乳汁点、斑片状强回声形成混合性潴留囊肿。绝经后乳管变小，多年淤乳成干结或粉末，导管或实质内呈粗颗粒状或多条强回声带。结论:乳腺乳汁淤积声像图随乳腺生理阶段变化，与积乳时间、吸收、浓缩、干燥有关。 |

| Abstract: |
| Objective:To observe the ultrasound characteristics of galactostasis at various physiological stages,so as to improve the diagnosis of galactostasis.Methods: The ultrasound data of 56 patients with galactostasis were retrospectively analyzed and the ultrasound characteristics were summarized.The ultrasonic manifestations of different physiological stages were compared.Results: During the lactation period,there were extensive mammary duct ectasias and floating weak signals were found in the mammary duct during pure galactostasis; large non-responsive fluid areas exhibited formations of honeycomb-like multilocular fibrous septa; and these cavities ruptured with abscess when secondary infection occurred.During the later lactation period,the dilated galactophores became hypoechoic or anechoic,which,together with the dot-like echoes of residual breast milk or macular strong echoes, formed mixed signals of retention cysts.After menopause,the galactophores atrophy occurred; the accumulation of galactostasis desiccated into patches or powder,which caused thick hyperechoic dots or multiple hyperechoic streaks in the galactophores or parenchyma.Conclusion: Ultrasonic images of galactostasis vary with the physiological and pathological changes of the mammary glands,and are related to the duration of galactostasis,absorption,concentration and desiccation of lactation. |
