摘要
目的:总结乳腺癌的X线征象,分析误诊原因,提高对乳腺良恶性病变X线征象的认识。方法:搜集以乳腺肿块就诊的乳腺疾病患者300例,从中选出术后病理诊断为乳腺癌的病例28例,良性病变6例;误诊病例6例。误诊病例中4例病理报告为良性而X线诊断为恶性肿瘤,包括纤维瘤2例,浆细胞性乳腺炎1例,特发性肉芽肿性炎1例;2例病理报告为乳腺癌而术前误诊为良性病变。分析乳腺癌及误诊病例的X线表现,总结误诊原因。结果:乳腺癌高发年龄段为41～50岁,多位于外上象限,大多数可见肿块影,边界模糊,有沿导管分布的泥沙样、断针样钙化,病侧血管增粗;4例误诊的良性病例因具有部分恶性病变特征而误诊,回顾分析时可见它们与恶性肿瘤的不同之处在于无明显肿块影,钙化点较粗大且分布不规则;2例因肿块边界清晰而误诊为良性病变,回顾分析时见其部分边界不清,且伴病侧血管及Cooper韧带增粗等恶性征象。结论:仔细分析钼靶X线病变特征并结合临床资料可提高乳腺良恶性肿块的诊断诊断符合率。
Objective:To improve cognition of mammografic signs of breast disease by analyzing the cause of misdiagnosis.Methods:Among 300 patients with abnormal breast mass,28 cases whose pathologic diagnosis were breast cancer and 6 misdiagnosis cases were selected.In these misdiagnosis cases,4 cases whose pathologic diagnosis were benign lesions,including fibroadenoma (2 cases),chronic inflammation (1 case),idiopathic granulomatous mastitis (1 case),were diagnosed as breast cancer on mammography and 2 cases whose pathologic diagnosis were cancers were diagnosed as benign lesions.the mammografic signs of cancers and misdiagnosis cases were analyzed and the cause of misdiagnosis summarized.Results:There was a high incidence of breast carcinoma in the age group range 41～50 years.The outer-upper quadrant of the breast is the major location of lesion.The mass was the main type of lesion,with illdefined border and malignant calcifications.4 misdiagnosed benign cases had no mass and irregular calcifications.2 misdiagnosed malignant cases had partially illdefined border.Conclusion:Combining the mammografic character with clinical data,breast lesions can be identified correctly.
