摘要 目的 探讨高频超声对肉芽肿性乳腺炎的诊断价值。 方法 回顾性分析106例经手术或粗针穿刺活检病理确诊为肉芽肿性乳腺炎的超声表现，肉芽肿性乳腺炎依据超声表现不同可分为低回声结节（或）肿块型、弥散分布型、混合回声型。 结果 106例肉芽肿性乳腺炎共115个病灶中，高频超声诊断肉芽肿性乳腺炎良恶性的准确率为62.6%，其中低回声结节(或)肿块型为31.5%，弥散分布型为71.4%，混合回声型为81.6%。 结论 肉芽肿性乳腺炎超声声像图缺乏特异性，其良恶性诊断正确率与超声分型有关，综合评价分析有助于提高疾病诊断的准确率。 Abstract：Objective To explore the value of high-frequency ultrasound in the diagnosis of granulomatous mastitis (GM). Methods A retrospective analysis was performed on the ultrasound findings of 106 patients with GM pathologically confirmed by surgery or core needle biopsy. GM was divided into hypoechoic nodular/mass type, diffused type, and mixed-echo type based on their ultrasound appearance. Results Among the 115 lesions in the 106 cases with GM, the accuracy of high-frequency ultrasound in the diagnosis of benign and malignant GM was 62.6%, 31.5% for hypoechoic nodular/mass type, 71.4% for diffused type, and 81.6% for mixed-echo type. Conclusion Due to the lack of specificity for GM, the accuracy of ultrasound in the diagnosis of benign and malignant GM is related to its ultrasound classification. Comprehensive evaluation and analysis help increase the diagnostic accuracy
