| 目的 探讨乳腺纤维腺瘤的非典型声像图特征并分析误诊原因。方法 回顾性分析经病理证实的485例（共493个病灶）乳腺纤维腺瘤患者的超声检查资料，分析其非典型声像特征，并计算误诊率；比较具有多种非典型特征与不具有或仅具有单一非典型特征病灶、不同大小病灶及不同病理类型病灶误诊率的差异，并分析误诊原因。结果 超声正确诊断404个病灶，其中99个表现为非典型声像；误诊89个，均为非典型声像；具有≥2种非典型特征病灶误诊率高于<2种非典型特征病灶（χ2=256.40，P<0.05），最大径>3 cm病灶误诊率高于≤3 cm病灶（χ2=6.73，P<0.05），复杂型纤维腺瘤误诊率高于非复杂型（χ2=188.01，P<0.05）。结论 具有多种非典型声像特征、体积较大、属复杂型纤维腺瘤的病灶易误诊。 |

| Objective To explore the atypical ultrasonic appearances of breast fibroadenoma and analyze the cause of misdiagnosis. Methods A total of 493 lesions in 485 patients of breast fibroadenoma detected by ultrasound examination and confirmed by pathology were retrospectively analyzed. Atypical appearances were analyzed and misdiagnosis rate were calculated. Statistical methods were taken to compare the misdiagnosis rates in lesions with various atypical appearances and those with none or single atypical appearance. Misdiagnosis rates in lesions with different sizes and pathological types were analyzed statically. Then misdiagnosing causes were analyzed. Results A total of 404 lesions were diagnosed correctly, including 99 lesions with atypical appearances, and the other 89 lesions were misdiagnosed, which showed atypical appearances. The misdiagnosis rate of lesions with≥2 atypical features was higher than that with none or single atypical feature (χ2=256.40, P<0.05). Large lesions (maximum diameter>3 cm) showed higher misdiagnosis rates than small ones (maximum diameter≤3 cm, χ2=6.73, P<0.05), and complex fibroadenoma lesions also showed higher misdiagnosis rate than simple ones (χ2=188.01, P<0.05). Conclusion The lesions with various atypical appearances, large size and complex fibroadenoma in pathology are easy to be misdiagnosed. |
