摘要
目的明确乳腺疾病的ＣＴ征象，评价ＣＴ扫描在乳腺癌及腋窝淋巴结转移诊断中的价值。材料与方法报告乳腺疾病５３例，包括乳腺癌３０例，良性疾病２３例，均行ＣＴ扫描，其中４４例同时进行钼靶摄影。结果（１）乳腺癌ＣＴ表现为：圆形、椭圆形或不规则形肿块，边缘毛刺，导管牵拉征，库伯韧带受累，局部皮肤胸壁浸润及周围脂肪间隙变形。良性疾病：单纯增生表现为不规则形肿块及患侧腺体增厚；囊性增生典型表现为多发圆形含液体密度囊肿。（２）ＣＴ与钼靶摄影结果相比较，两者在良恶性乳腺疾病的鉴别方面具有相同价值。但在肿块靠近腋窝或胸壁等情况下，ＣＴ较钼靶更为实用；并且ＣＴ有助于乳腺癌腋窝淋巴结转移的诊断。结论ＣＴ扫描在乳腺病变的发现、病变良恶性的鉴别诊断以及腋窝淋巴结转移的诊断方面有很大价值。
Purpose To study the CT signs of breast dieases, and discuss the value of CT in the diagnosis of breast cancer and the axillary lymph node(LN) metastases. Materials and methods Fifty-three cases were reported ,including breast cancer 30 cases and benign diseases 23 cases.CT were performed in all patients, 44 also had mammography examination. Results (1)The CT appearance of breast cancer:round or irregular mass,spiculated border,duct retraction,involved Cooper's ligament, deformed adipose space etc. Benign hyperplasia:irregular mass and symmetrical thickening of breast glands.Cystic hyperplasia:typically multiple,round,liquid density mass. (2)CT was comparable to mammography in terms of differential diagnosis, however with breast mass located near the axilla or for evaluation of the thoracic wall. CT was superior to mammography. CT was also helpful in detecting LN metastases. Conclusion CT is valuable in detecting and differentiating breast diseases as well as in the diagnosis of LN metastases.
