乳腺单纯性浸润性小叶癌的临床、X线、超声特征

Clinical,mammographic and sonographic features of pure invasive lobular breast carcinoma

目的观察乳腺单纯性浸润性小叶癌(ILC)的临床、X线和超声检查特征,评价联合应用三种方法的价值。方法回顾55例经手术病理证实为单纯性ILC的详细检查结果,分析得出假阴性结果的原因。结果主要临床检查结果为肿块(96.15%)和腺体增厚(3.85%)。主要X线检查结果为边缘不规则肿块(65.38%)和结构扭曲(23.08%)。主要超声检查结果为肿块(98.00%)和结构紊乱(2.00%)。临床、X线、超声对病灶的定性诊断准确率分别为94.55%、83.87%、98.04%,联合应用的准确率为100%。结论超声检测ILC病灶的准确性高于X线检查。联合应用临床、X线、超声可提高ILC的术前诊断准确率。

Objective To observe the clinical,mammographic and sonographic features of pure invasive lobular breast carcinoma （ILC）,and to explore the value of combined imaging assessment of ILC. Methods Sonographic appearances of 55 patients of ILC were retrospectively reviewed in correlation with mammographic,pathologic and clinical findings,and the causes of false negative were analyzed. Results The main features found in clinical examination were mass （96.15%） and thickening in the size of breast （3.85%）. The main mammographic features were spiculated or ill-defined mass （65.38%） and architectural distortion （23.08%）. The most common sonographic patterns were mass （98.00%） and distortion （2.00%）. The accuracy for detecting ILC of clinical examination,mammography and ultrasonography was 94.55%,83.87% and 98.04%,respectively,while combining the three modalities,the detection rate increased to 100%. Conclusion Sonography has higher accuracy than mammography in detecting ILC. Combining clinical examination,mammography and ultrasonography can increase the pre-operative diagnostic accuracy of ILC.
