目的探讨全数字化乳腺摄影之肿块“边缘征”对乳腺肿块良、恶性病变的定性诊断价值。方法回顾性分析95例女性乳腺肿块患者,年龄24~80岁,平均50.9岁,所有病例均经手术病理证实。对全数字化乳腺摄影显示乳腺肿块之“边缘征”进行分析,将边缘深分叶状、浸润状、星芒状归为恶性边缘组,将边缘清晰、小部分边缘模糊归为良性边缘组。结果病理诊断良性32例,恶性63例。影像诊断与病理结果对照,恶性被误诊为良性5例,占7.9%,良性被误诊为恶性6例,占18.8%。依据“边缘征”诊断乳腺肿块的敏感性、特异性、准确性分别为92.1%、81.3%、88.4%。结论数字化乳腺摄影肿块之“边缘征”可作为乳腺良、恶性肿块定性诊断的重要征象之一,便捷且准确,有较高诊断价值及重要临床价值。
Objective To investigate the value of qualitative diagnosis of benign and malignant lesions of breast masses with digitalized mammography mass and marginal sign. Methods A retrospective analysis of 95 cases of female breast lumps, aged 24 to 80 years, mean 50.9 years old, all cases were confirmed by surgical pathology. The analysis of the “digital sign” of breast tumors in the digitalized mammography showed that the deep edge lobed, infiltrated, and stellate shape were classified as malignant edge group, and the edge was clear and a small part of edge blur was classified as benign edge group . Results The pathological diagnosis of benign 32 cases, 63 cases of malignant. Imaging diagnosis and pathological findings, malignant was misdiagnosed as benign in 5 cases, accounting for 7.9%, benign were misdiagnosed as malignant in 6 cases, accounting for 18.8%. The sensitivity, specificity and accuracy of diagnosis of breast masses based on “marginal sign ” were 92.1%, 81.3% and 88.4% respectively. Conclusion Digital mammography “marginal sign” can be used as one of the important signs of qualitative diagnosis of benign and malignant breast masses. It is convenient and accurate, has high diagnostic value and important clinical value.
