目的 :探讨乳腺X线立体定位细针活检技术诊断不可触及的乳腺病灶的价值。材料和方法 :对 2 7例临床不能触及 ,而X线片上显示的乳腺微小病变 ,通过X线立体定位穿刺 ,放入钢丝定位后指导外科切检 ,进行组织病理学检查。结果 :2 7个乳腺病变 ,恶性病变 7例 ,其中T0 期 3例 ,T1期 4例 ;良性病变 2 0例 ,含慢性囊性乳腺病 10例 (其中合并导管上皮异型增生及上皮增生活跃各 3例 ) ,小叶增生 3例 ,慢性炎症 3例 ,腺纤维瘤 2例 ,导管内乳头状瘤 1例 ,错钩瘤 1例。结论 :立体定位细针活检对不可触及的乳腺病变的定位定性诊断以及对早期乳腺癌的诊断有重要价值。
Objective: To investigate the value of breast X-ray stereotactic fine needle biopsy in the diagnosis of non-palpable breast lesions. MATERIALS AND METHODS: Twenty-seven cases of clinically unreachable breast lesions and minimal breast lesions showed on the X-ray films were examined by X-ray stereotactic puncture and wire placement to guide surgical examination and histopathology examination. RESULTS: Twenty-seven breast and malignant lesions were found in 7 cases, including 3 cases of T0 and 4 cases of T1, 20 cases of benign lesions and 10 cases of chronic cystic mammary disease (including those with ductal dysplasia and epithelial hyperplasia 3 cases), 3 cases of lobular hyperplasia, 3 cases of chronic inflammation, 2 cases of adenofibroma, 1 case of intraductal papilloma and 1 case of false hook tumor. Conclusion: Stereotactic fine needle biopsy has important value in the localization diagnosis of non-palpable breast lesions and in the diagnosis of early breast cancer.
