213例浆细胞性乳腺炎的超声表现及漏误诊原因分析

Ultrasonographic manifestations of plasma cell mastitis in 213 cases and analysis on the reasons of missed diagnosis and misdiagnosis

摘要:

目的：总结浆细胞性乳腺炎（plasma cell mastitis，PCM）的超声表现并分析其超声漏误诊原因。方法：回顾性分析经病理确诊的213例ＰＣＭ的超声表现及超声漏误诊原因。结果：213例中超声检出病灶者209例，其中局限性病灶195例，均为单发病灶，14例为弥漫性导管扩张。超声诊断为ＰＣＭ者48例，诊断正确率22.54%，误诊40例，误诊率18.78%，漏诊4例，漏诊率1.88%。209例患者超声表现为单纯导管扩张14例、单纯囊肿22例、实性肿块110例、囊实混合肿块63例，146例病灶内部探及血流信号，其中94例血流丰富。结论：ＰＣＭ超声表现复杂多样，诊断较困难，极易漏误诊，仔细观察声像图并结合临床表现，有望提高超声诊断正确率。

Abstract:

Objective：To summarize ultrasonographic manifestations of plasma cell mastitis in 213 cases and to analyze reasons of missed diagnosis and misdiagnosis. Methods：Ultrasonographic manifestations of 213 cases of plasma cell mastitis testifed by pathology and reasons of missed diagnosis and misdiagnosis were retrospectively studied. Results：Among 213 cases，209 cases were detected lesions by ultrasond，including 195 limited and single lesions and 14 ductal ectasia lesions. Forty-eight cases were diagnosed as plas－ma cell mastitis by ultrasond and diagnosis accuracy rate was 22.54%；40 cases were misdiagnosed，misdiagnosis rate was 18.78%；4 cases were missed diagnosed，missed diagnosis rate was 1.88%.Utrasonographic manifestations of 209 cases included：ductal ectasia in 14 cases，cyst in 22 cases，solid nodule in 110 cases and mixed cystic and solid nodule in 63 cases. Internal blood flow signals were detected in 146 cases，rich in 94 cases. Conclusions：Ultrasonographic manifestations of plasma cell mastitis are varied and complex and it is uneasy to make correct diagnosis. Careful observations of ultrasonographic manifestations combined with clinical features are required in order to improve the diagnosis accuracy.
