目的 评价乳腺少见肿瘤的影像学特点。方法 回顾分析经手术及病理证实 11例少见乳腺肿瘤影像学表现。结果 11例乳腺肿瘤中 ,非何杰金氏淋巴瘤 1例 ,恶性多形性腺瘤 1例 ,乳腺原发性鳞癌 1例 ,骨肉瘤 1例 ,叶状囊肉瘤 2例 ,错构瘤 5例。骨肉瘤特征表现为 :肿块中有象牙骨组织 ,恶性多形性腺瘤表现为较大肿块 ,边界清楚 ,周边血管增粗。叶状囊肉瘤为低度恶性肿瘤 ,病程长 ,肿块大 ,边界清楚 ,内有粗大钙化 ,周围有宽窄不一透亮带 ,通常无腋下淋巴结转移。错构瘤的特征表现是 :瘤体密度高度不均 ,高密度区域呈岛屿状分布 ,包膜完整。原发性乳腺鳞癌及非何杰金氏淋巴瘤无特征性表现。结论 乳腺少见肿瘤影像无明显特征性 ,需综合分析才有可能作出定性诊断
Objective To evaluate the imaging features of rare breast tumors. Methods Retrospective analysis of 11 cases of rare breast tumors confirmed by surgery and pathology. Results Of the 11 breast tumors, 1 non-Hodgkin’s lymphoma, 1 malignant pleomorphic adenoma, 1 primary breast squamous cell carcinoma, 1 osteosarcoma, 2 cystosarcoma, 5 hamartoma example. Osteosarcoma characterized as: lumps in the bone tissue, malignant pleomorphic adenoma showed larger lumps, the border is clear, peripheral vascular thickening. Phyllosarcoma sarcoma is a low-grade malignancy, long course, large lumps, clear boundaries, there are coarse calcification, there are varying width around the translucent band, usually without axillary lymph node metastasis. Hamartoma features are: high heterogeneity of tumor density, high density region was island-like distribution, complete capsule. Primary breast squamous cell carcinoma and non-Hodgkin’s lymphoma without characteristic manifestations. Conclusion There is no obvious characteristic of rare breast tumor image, it is necessary to make a comprehensive analysis to make a qualitative diagnosis
