摘　　要：目的研究乳腺髓样癌的X线表现,并比较不同病理分型的X线特点,提高对该病的影像诊断水平。方法回顾性分析经手术病理证实、有完整乳腺X线资料的乳腺髓样癌32例共33个病灶,其中典型髓样癌27个病灶,不典型髓样癌6个病灶;观察其X线特点。结果 33个病灶中表现为不伴钙化的肿块30个(90.9%),伴钙化肿块2个(6.1%),局灶性密度不对称1个(3.0%)。32个肿块形状以圆形和分叶状最为多见,分别占37.5%(12/32)。边缘主要表现为浸润状和微小分叶状,分别占40.6%(13/32)和34.4%(11/32)。肿块表现为高密度占65.6%(21/32),等密度34.4%(11/32)。典型髓样癌和不典型髓样癌在肿块形状、边缘及密度改变上无明显差异,P值分别为0.200、0.083、0.330。结论乳腺髓样癌X线表现以圆形或分叶状高密度肿块为主要特点,很少伴有钙化。典型髓样癌和不典型髓样癌在X线上无法鉴别。Objective To analyze the mammographic features of breast medullary carcinoma and evaluate the value of mammography in distinguishing atypical from typical medullary carcinoma. Methods Mammographic findings in 32 women with medullary carcinomas （33 lesions） , including 27 typical and 6 atypical medullary carcinomas, were retrospectively studied. Results The most frequent mammographic features of medullary carcinoma was the mass （32/33） without （30/33, 90. 9% ） or with calcification （2/33, 6. 1% ）. Focal asymmetric density was seen in 1 lesion （1/33, 3.0% ）. Most masses showed a round （12/32, 37.5% ） or lobular （12/32, 37.5% ） shape, with indistinct （ 13/ 32, 40. 6% ） or microlobulated （11/32, 34.4% ） margin. No obvious difference was found in tumor＇s shape （P = 0. 200）, margin （P = 0. 083）, and density （P = 0. 330） between the typical and the atypical madullary carcinomas. Conclusion At mammography, medullary carcinoma is usually presented an uncalcified mass with microlobulated or indistinct margins. Mammpgraphy can not reliably distinguish atypical from typical medullary carcinomas.
