乳腺单纯性囊肿的钼靶X线影像分析

目的提高乳腺X线摄影对乳腺单纯性囊肿诊断的认识。方法回顾2000-03～2004-0339例经手术、病理证实为乳腺单纯性囊肿的钼靶X线征象。结果39例56个乳腺单纯性囊肿患者:X线正确诊断为单纯性囊肿的23例,诊断为纤维腺瘤的10例,乳腺癌2例,肿块待查4例。正确率59.0%,误诊率41.0%。囊肿X线表现:呈圆形12个,卵圆形38个,轻度分叶状4个,慧星尾状肿块2个。囊肿边界清楚、锐利26个,部分清楚、部分模糊27个,全部模糊3个。囊肿密度均匀54个,伴有钙化2个。其中囊肿长轴垂直于胸壁20个,指向乳头方向18个。囊肿加压后变形4个。结论仔细分析乳腺单纯性囊肿的X线征象有助于提高对本病诊断的准确性。

Radiographic Analysis of Simple Cyst of the Breast

Objective To make a further understanding of mammographic features of simple cyst of the breast (SCB).Methods Molybdenum target radiographic signs in 39 cases with SCB proved pathologically and were retrospectively analyzed. Results Of the 56 SCB in 39 cases, 23 were diagnosed rightly as SCB, 10 as fibroadenoma, 2 as cancer and the remaining 4 were undefined. The diagnostic accuracy and misdiagnosis were 59.0% and 41.0% respectively. Radiograph showed round in 12, ovoid in 38, mild lobed in 4 and comet tail form in 2. The borders of cyst were distinct and sharp in 26, distinct partly and indistinct partly in 27,indistinct completely in 3. The density was homogeneous in 54 with calcifications in 2. Of the 56 SCB, the length axes of cyst were upright to chest wall in 20 and towards nipple in 18. The cysts could be transformed with pressure in 4.Conclusion Careful analysis of radiographic features of SCB is helpful for diagnosing accurately this disease.
