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。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 .
