早期乳腺癌的钼靶X线表现及误诊分析

摘要

Objective To investigate mammographic features of early breast cancer and to increase the correct diagnostic rate so as to decrease misdiagnosis. Methods 68 cases of early breast cancer proved by operation or aspiration biopsy are ana-lyzed retrospectively. Results Of the 68 cases of early breast cancer,14 cases were dense gland type,21 more gland type,23 less gland type and 10 fat type. Among the 68 patients,25 cases showed tiny calcification(36. 76%),23 cases mass(33. 82%),9 ca-ses focal architecture distortion(13. 23%),5 cases small focus of increased density(7. 35%),3 cases anomalous duct(4. 41%) and 3 cases showed distended blood vessel(4. 41%). 15 cases were misdiagnosed(22. 06%)before operation or aspiration biopsy. Conclusion Mammographic manifestations of early breast cancer are atypical and diagnosis is often affected by the glandular types. Combination of clinical manifestations and radiological features can decrease misdiagnosis.%目的：探讨早期乳腺癌的钼靶X线表现，进一步提高该病的影像诊断水平，减少误诊。方法回顾性分析68例经手术或穿刺活检病理证实的早期乳腺癌的钼靶X线片。结果68例早期乳腺癌发生于致密腺体型14例，多量腺体型21例，少量腺体型23例，脂肪型10例。 X线表现为微小钙化25例(36.76%)，肿块影23例(33.82%)，结构紊乱9例(13.23%)，局部密度增高影5例(7.35%)，乳管造影异常3例(4.41%)，血管增粗3例(4.41%)。其中有15例发生误诊(22.06%)。结论早期乳腺癌的钼靶X线征象不典型，诊断易受腺体类型的影响，影像与临床紧密结合可有效减少误诊。
