摘要: 目的 探讨高频超声诊断乳腺微小癌的常见误诊原因。方法 回顾性分析经病理证实的90例乳腺微小癌的超声征象,根据病灶最大径,分为0.5-1.0cm组55例和≤0.5cm组35例,两组又分别分为正确提示组与误诊组。采用西门子公司SIEMENZ S2000型、GE公司vivid7及vivid9大型彩色多普勒超声仪器,仔细观察二维声像图结果,分析其误诊原因。结果 90例乳腺微小癌,误诊32例,病灶最大径0.5-1cm组与≤0.5cm组误诊原因边界具有统计学意义(p<0.05)。其中最大径在0.5-1.0cm组的病灶在边界、微钙化在正确提示组与误诊组之间差异有统计学意义(p<0.05)。最大径≤0.5cm 组病灶,其中纵横比、多发结节在其正确提示组与误诊组之间差异有统计学意义(p<0.05)。结论 乳腺微小癌的误诊原因在不同病灶大小之间有所不同,病灶最大径在0.5-1cm时表现为边界清晰,无微钙化等良性结节声像图特征时容易误诊,而最大径在≤0.5cm时表现为纵横比<1、多发结节特征时容易误诊。

Abstract:

[Abstract] Objective   To evaluate the possible causes of misdiagnosis of minimal breast carcinoma (MBC). Methods   The possible causes of misdiagnosis of 90 cases of MBC confirmed by pathology were retrospective analyzed. Accord? ing to the maximum diameter of the lesion, 90 cases were divided into 0.5-1.0 cm group (n=55) and ≤0.5 cm group (n=35). And these two groups were subdivided into correct and misdiagnosed groups. The two-dimensional ultrasound findings were observed by using SIEMENZ S2000, GE vivid7 and GE vivid9 color Doppler ultrasound instruments, and reasons of misdiag? nosis were analyzed. Results  There were 32 cases were misdiagnosed in 90 patients with MBC. There was significant differ? ence in boundary of misdiagnosis between diameter 0.5-1.0 cm group and ≤0.5 cm group. There were significant differences in boundary and calcification between misdiagnosed group and correct group in diameter 0.5-1.0 cm group (P < 0.05). There were also significant differences in A/T ratio and accompanying by multiple benign nodules between misdiagnosed group and correct group in diameter ≤0.5 cm group (P < 0.05). Conclusion The misdiagnosis in MBC is because of different lesion sizes. The misdiagnosis happens in the maximum diameter of the lesions between 0.5-1.0 cm that showed manifestation of sharp edges, no micro-calcification in sonographic features of benign. The misdiagnosis happens in maximum diameter of le? sions ≤ 0.5 cm that manifested as the aspect A/T ratio <1 and characterized by multiple nodules
