Figure 5a.  Invasive ductal carcinoma in a 40-year-old woman with a bloody nipple discharge. (a) Conventional ductogram shows a dilated and obstructed duct (arrowheads) with an irregular wall and multiple filling defects with irregular surfaces. A cyst with a filling defect (arrow) communicates with the discharging ductal system. (b) MR ductogram (maximum intensity projection [MIP] image) shows multiple cystic and irregularly dilated ducts. The cystic areas appear as high-signal-intensity nodules. (c) MR mammogram (MIP image) shows a diffusely enhancing area (arrows), which represents an invasive ductal carcinoma. (d) Three-dimensional fusion image shows the extent of the carcinoma (yellow) surrounding the dilated ducts (green).
