目的 :探讨乳腺巨大肿瘤的声像图、CDFI表现特征及其鉴别诊断。方法 :对 13例经病理证实为巨纤维腺瘤、叶状囊肉瘤、乳腺癌的声像图与CDFI表现进行回顾性分析。结果 :5 / 6例巨纤维腺瘤边界清楚 ,轮廓规则 ,包膜完整 ,2 / 2例叶状囊肉瘤呈分叶状 ,以实性为主 ,部分囊性。 5 / 5例乳腺癌有典型的恶性肿瘤特征 ,伴腋窝淋巴结转移 ,1/ 5例的肝转移。CDFI:6例巨纤维腺瘤血供Ⅱ～Ⅲ。 2例叶状囊肉瘤血供Ⅲ级 ,3例乳腺癌血供Ⅱ～Ⅲ级 ,2例乳腺癌血供Ⅰ级。结论 :巨纤维腺瘤、叶状囊肉瘤、乳腺癌各自有典型的声像图特征 ,是诊断与鉴别诊断的主要依据 ,对于乳腺巨大肿瘤良、恶性判断CDFI血供丰富程度可供参考。
Objective: To investigate the ultrasonography of giant breast tumors, CDFI features and their differential diagnosis. Methods: Thirteen cases confirmed by pathology were giant fibroadenoma, phyllodes sarcoma, breast cancer and CDFI sonographic features were retrospectively analyzed. Results: 5/6 cases of giant fibroadenoma had clear boundary, regular outline and complete capsule, and 2/2 phyllodes sarcoma were lobulated, mainly solid and partially cystic. Five out of five breast cancers had typical malignant features, with axillary lymph node metastases and 1 in 5 liver metastases. CDFI: Six cases of giant fibroadenoma blood supply Ⅱ ~ Ⅲ. Two cases of phyllodes sarcoma blood supply grade Ⅲ, 3 cases of breast cancer blood supply Ⅱ ~ Ⅲ grade, 2 cases of breast cancer blood supply Ⅰ grade. CONCLUSION: Giant fibroadenoma, cystosarcoma and breast cancer each have typical sonographic features. They are the main basis of diagnosis and differential diagnosis. The richness of CDFI blood supply can be judged by the judgment of benign and malignant breast tumors.
