摘　　要：目的评价乳腺钼靶摄影显示腋窝淋巴结增大在乳腺疾病诊断中的价值。方法对79例女性乳腺疾病患者行乳腺钼靶摄影检查，全部病例行常规乳腺轴、斜位投照，部分病例加照腋下加压位。分析其淋巴结X线特点，并与病理结果进行对照。结果79例中，乳腺癌46例、纤维腺瘤7例、浆细胞乳腺炎2例，脂肪瘤2例、乳管内乳头状瘤2例，乳腺增生症20例。33例乳腺良性疾病（乳腺增生病、纤维腺瘤、脂肪瘤等）双侧腋窝淋巴结显影12例，数目1～5枚，31例直径〈2cm，13例有偏心性脂肪中心，周围脂肪线清晰；46例乳腺癌淋巴结中43例仅为患侧显影，数目1～4枚，17例直径≥2．0cm，全部淋巴结致密均匀，周围脂肪线消失。并且2组间在淋巴结位置、数目、直径、密度上均有统计学差异。结论乳腺癌和乳腺良性疾病的钼靶X线显示的腋窝淋巴结各有其特点，两者具有一定的影像学差异，可以作为2类疾病鉴别诊断的辅助指标。Objective To evaluate the value of breast molybdenum target radiography in evaluating the enlarged axillary lymph nodes in breast diseases. Methods 79 patients underwent breast molybdenum target radiography,including conventional laxial and oblique projection. Some of them were examine furtheremore in compress projection in axillary fossa. The X - ray findings were analysis. And radiologic - pathologic correlation were carried out. Results There were 46 cases of brease carcinoma, 20 cases of hyperplasia,7cases of fibroadenoma,2 cases of plasmacytic mammitis,2cases of lipoma and 2 cases of papilloma in 79 patients. In the 33 cases of breast benign lesion , the enlarged axillary lymph nodes were seen bilaterally in 12 cases, sum was 1 to 5 in each case, smaller than 2 cm in diameter in 31 cases and uneven density in 13 cases were showed. In the 46 cases of brease carcinoma, the enlarged lymph nodes were seen laterally in 43cases, sum was 1 to 4 in each cases, larger than 2 cm in diameter was showed in 17 cases, and all were even density. There were statistical differences in number, diameter and density of enlarged lymph nodes between two groups. Conclusion The enlarged axillary lymph nodes are of different X - ray features in breast benign lesion and malignant lesion,it is helpful in differential diagnosis of breast diseases.
