目的探讨乳腺错构瘤的影像学表现。方法收集15例经病理证实的乳腺错构瘤资料,分析其钼钯、彩超及CT检查的影像学表现及病理结果并复习文献。结果15例中,脂肪型(3例)、纤维型(3例)及混合型(9例)。结论乳腺错构瘤的影像学表现因其内部组织结构不同而有差异,但典型病例其影像学表现具有特征性。因此临床要仔细分析病例,进行鉴别诊断,以提高对乳腺错构瘤诊断的准确率。 Objective To investigate the imaging findings of breast hamartoma. Methods Fifteen cases of pathologically confirmed breast hamartoma were collected, and the imaging findings and pathological findings of molybdenum-palladium, color Doppler ultrasonography and computed tomography were analyzed and reviewed. Results Among the 15 cases, 3 were fat type, 3 were fibrous type and 9 were mixed type. Conclusion The imaging findings of breast hamartoma are different due to the different internal tissue structure. However, the typical cases have characteristic imaging features. Therefore, careful analysis of clinical cases, differential diagnosis to improve the accuracy of the diagnosis of breast hamartoma.
