• Adenoma of the nipple
• Contrast-enhanced magnetic resonance imaging
• Breast

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 x 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.
