摘要
目的统计在胸部CT图像上偶然发现的乳癌病变的发病率，并分析其CT特征以及临床意义。方法收集6674例女性胸部CT图像，记录偶然发现的乳癌病变并探讨其CT特征。结果共有19例（0．28％）在CT上发现乳癌病变，这些病变的CT特征包括：病灶外缘呈分叶状或毛刺征12例、病灶内含微小钙化点3例、腋窝淋巴结稍大3例；12例行增性扫描者强性化程度为20～60HU，强化高于40HU行有8例，其中均匀强化5例、不均匀强化7例；另有3例在CT上漏诊。结论在胸部CT扫描时可能会偶然发现乳癌，必须注意观察乳腺的情况。提高对乳癌基本CT征象的认识是减少误诊的保证，对乳癌的早期诊断及提高生存质量也有帮助。
Objective To count the frequency of incidental finding of breast cancer by Chest CT,and discuss the features of CT images. Methods The thorac.ic CT images of 6674 female patients were collected and analyzed. The cases with incidental finding of breast cancer by Chest CT were fihered and the features of CT images were recorded. Results Total 19 patients（0.28% ） were incidentally found with breast cancer. The CT futures of those lesions included： focus outer margin was lobulated with spicules in 12 cases, microcalcifications in focus in 3 cases, slightly enlarged axillary lymph node in 3 cases. The enhancement scan（ from 20 HU to 60 HU） was performed in 12 cases,in which more than 40 HU 8 cases. Homogenous enhancement was found in 5 eases,and heterogeneous enhancement in 7 cases. 3 cases were missed by CF. Conclusion Breast cancer can be incidentally found on chest CT images. We should pay more attentions on the futures of mammary gland . To raise awareness of basic CT signs of breast cancer should reduce the misdiagnnsis rate of breast cancer,and improve the early diagnosis of cancer and quality of life of patients.
