A woman in her 50s was referred to our hospital for an investigation of a right breast tumor. The tumor was palpated below the nipple, but there was no erosion or nipple discharge. Mammography showed a well-defined high-density tumor, measuring 2 cm in diameter, without calcification, and ultrasonography showed a low-echoic mass with a fluid component with posterior echo enhancement and a lateral shadow. Contrast-enhanced magnetic resonance imaging (CE-MRI) demonstrated a 1.3 × 0.8 cm solid component and a gradually increasing time-intensity curve. We performed lumpectomy and the pathological findings were adenoma of the nipple. The pattern of the time-intensity curve might be attributed to moderate fibrosis of the tumor. Contrast-enhanced MRI is therefore considered to be very useful in the diagnosis of breast disease because it can show the nature and extent of the breast lesion; however, we should be aware that various patterns have been observed on CE-MRI for adenoma of the nipple.
一位 50 多岁的女性因右乳肿瘤到我院就诊。肿瘤触诊位于乳头下方，但无糜烂或乳头溢液。乳腺 X 线摄影显示边界清楚的高密度肿瘤，直径 2 厘米，无钙化，超声显示低回声肿块，有液性成分，后方回声增强，外侧有阴影。增强磁共振成像（CE-MRI）显示 1.3×0.8 厘米的实性成分和逐渐增加的时间-强度曲线。我们进行了乳房肿瘤切除术，病理结果为乳头腺瘤。时间-强度曲线的模式可能归因于肿瘤的中度纤维化。因此，增强磁共振成像被认为对乳腺疾病的诊断非常有用，因为它可以显示乳腺病变的性质和范围；然而，我们应该意识到，在 CE-MRI 上观察到了各种模式的乳头腺瘤。
