乳房肿块的超声诊断价值

Ultrasonography Used in Diagnosis of Breast Tumor

本文报告２５０例共３１７只乳房肿块的超声检查资料，所有病例均经手术和病理证实。乳腺癌诊断符合率为８１．４１％，腺瘤为８７．２５％。发现的最小良性病灶４×５ｍｍ，最小癌６×６ｍｍ。本文就乳癌的早期发现、良恶性病灶的鉴别及部分病例误诊原因分析等几方面作了讨论。作者认为高分辨率、高频探头的应用为乳腺内小病灶的发现提供了基础。肿块的边界、包膜及形态是鉴别良恶性病灶的首要标准。而彩色多普勒信号仅能在此基础上起辅助作用。对发现的不能明确其性质的病灶可在超声引导下穿刺活检。

In this study, 317 breast masses among 250 patients were examined with both B-mode sonography and excisional biopsy. The accordance rates of ultrasonography with biopsy were 81.4% in breast cancer and 87.25% in mastadenoma, The minimal detectable lesions with ultrasonography for benign and malignant tumors were 4×5mm and 6×6mm respectively. It is considered that high resolution and high frequency ultrasound has made it possible to detect small breast lesions with sonography. The margin, envelope and the shape of the tumor are of most importance to distinguish benign tumor from malignant one with this technique, and color Doppler signals are also helpful but only auxiliary. ultrasound guided needle biopsy is recommended when diagnosis is uncertain.Some aspects of misdiagnosis were also discussed in this paper.
