目的：探讨乳头状瘤Ｘ线平片、导管造影的Ｘ线表现及其与临床、病理的关系。材料与方法：回顾性分析２１例乳管内乳头状瘤的临床特点，乳房Ｘ线平片，导管造影表现及病理改变；并根据病变大小、形态，病变处导管形态及二者的关系，在导管造影片上进行Ｘ线分型且与病理改变进行对比。结果：２１例均有单个乳孔溢液，血性１８例，乳晕区触及肿块３例。乳房Ｘ线平片示乳晕下区肿块４例，左乳晕下区扩张导管１例。导管造影：２１例均示导管内充盈缺损，其中１９例并导管扩张。管内型９例，囊内型９例，实体型３例。Ｘ线表现与病理改变一致。结论：乳管内乳头状瘤最常见的临床表现是单个乳孔溢液，乳腺Ｘ线平片征象少；导管造影特点是管内充盈缺损，对乳头状瘤具有确诊价值。
OBJECTIVE: To investigate the X-ray manifestations of X-ray and ductal angiography of papilloma and its relationship with clinicopathology and pathology. Materials and Methods: A retrospective analysis of 21 cases of intraductal papilloma clinical features, mammography, catheter imaging and pathological changes; and according to lesion size, shape, lesion at the catheter morphology and the relationship between the two, in the catheter X-ray film made on the type and pathological changes were compared. Results: All 21 patients had a single breast overflow, bloody in 18 cases, and the areola area touching the mass in 3 cases. Mammograms showed 4 cases of tumor in the areola and 1 case of dilatation catheter in the left areola. Catheterography: Twenty-one cases showed intraductal filling defect, of which 19 cases and catheter dilatation. In-tube type in 9 cases, intracapsular type in 9 cases, solid type in 3 cases. X-ray findings and pathological changes. Conclusion: The most common clinical manifestation of intraductal papillomas is single breast overflow, the signs of mammography are few. The characteristic of catheter angiography is filled defect in the tube, which has definite value for papilloma.
