摘要
目的 通过多层CT对乳腺肿块性病变的显示及在诊断工作中的作用进行评价 ,探讨多层CT在乳腺肿块性病变的诊断价值。方法 收集临床、病理证实乳腺肿块性病变 3 2例 ,重点分析多层CT扫描及重建对肿块本身、淋巴结显示情况。结果 3 2例乳腺肿块中 ,2 2例乳腺癌表现为形态不规则、密度不均匀、边界不清肿块 19例 ,10例显示肿块周围水肿环 ,肿块邻近皮肤水肿 8例 ,乳头内陷、导管增粗 6例 ,8例肿块胸肌相连。腋下恶性淋巴结显示 12例 ,6例同时显示胸小肌后淋巴结 ,2例显示锁骨上淋巴结肿大。结论 多层CT扫描及重建技术对乳腺肿块内部结构、周围组织之间关系显示更为直接。对周围淋巴结尤其腋下淋巴结和胸肌后淋巴结的显示较为理想 ;可为影像医生和临床医生的准确诊断和正确治疗提供直观、形象、生动的图像信息。是一项简单、易行、准确的检查方法。
Objective To evaluate the manifestation characteristic of breast mass in multi slice CT, study the diagnosis value of this method in every kinds of breast masses. Methods Thirty two patients with clinical or histopathological verified as breast masses were examined by multi slice CT and reconstructed in MPR/VR or 3D. The imaging signs of breast lesions and axillary lymph node in multi slice CT were analyzed. Results Among the 32 cases, there were 22 cases of breast cancer, in which 19 manifested as irregular or spiculated masses with inhomogeneous and asymmetric density, 10 cases by dropsy of wreath around the neoplasms, skin thickening in 8, 6 cases manifested as nipple retraction and the duct dilatation. The axillary lymph node were positive in 12, in which 6 cases were found under the pectoralis minor muscle and above clavicle simultaneously. Conclusion MSCT is the best method for detecting and manifesting breast masses and metastatic axillary lymph nodes.
