【摘要】 目的:探讨乳腺神经内分泌癌的超声影像学特点。方法:回顾分析29例经病理确诊的乳腺神经内分泌癌患者病灶的超声影像学资料。29例中包括25例浸润性神经内分泌癌,4例原位神经内分泌癌。结果:26个肿块呈低回声,3个呈中等回声;23个肿块回声不均匀,6个回声均匀;23个肿块形态不规则,6个肿块形态规则。11个肿块内见细小钙化灶,1个肿块周围见高回声环。15个肿块见丰富或稍丰富血流,9个肿块见中等血流,3个肿块见少量血流,2个肿块未见明显血流。8个肿块行弹性超声检查,弹性评分结果:1分1个,3分2个,4分5个。乳腺肿块超声诊断符合率为97%(28/29);同侧腋窝淋巴结转移超声诊断符合率为75%(9/12)。结论:乳腺神经内分泌癌超声多表现为回声不均匀、形态不规则、瘤内见细小钙化灶、血流丰富、弹性评分高。灰阶超声、彩色超声及弹性超声的联合应用有助于病变的定性诊断。更多还原

【Abstract】 Objective:To investigate ultrasonographic features of neuroendocrine carcinoma of breast. Methods:The ultrasonographic features of twenty-nine patients with neuroendocrine carcinoma of breast confirmed by pathology were retrospectively analyzed.Among them,twenty-five cases were invasive neuroendocrine carcinomas while the other four cases were neuroendocrine carcinomas in situ.Results:Twenty-six lesions were hypoechoic while the other three were isoechoic.Twenty-three lesions were heterogeneous while the other 6 were homogeneous.The shape was irregular in twenty-three masses and regular in 6 masses. Microcalcification was found in 11 masses while hyperechoic halo was found in 1 mass.Hypervascular,isovascular,hypovascular and avascular images were found in 15,9,3,and 2 masses,respectively.Eight masses were examined by ultrasound elastography.According to elastography score,1,3,and 4 points were found in 1,2,and 5 masses,respectively.The accuracy rate of ultrasonographic diagnosis for breast mass was 97%(28/29).And the accuracy rate of ultrasonographic diagnosis for ipsilateral axillary lymph node metastases was 75%(9/12).Conclusions:Features such as heterogeneous echo,irregular shape,microcalcification inside mass,hypervascular image and high score on elastography are frequent for neuroendocrine carcinoma of breast.The combined application of gray-scale ultrasound,color Doppler ultrasound and ultrasound elastography may be conducive to the differential diagnosis of lesion.更多还原
