  		Figure 1. A focal mass arising from the ductal wall with relatively narrow base of attachment is present. Note the branching pattern and peripheral fronding typical of intraductal papilloma/papillary carcinoma (D-Duct).

  		Figure 2. Papillary carcinoma. A moderately large mass is seen to almost totally fill the entire dilated duct. Relatively hypoechoic debris is seen to fill the peripheral duct adjacent to the mass. A short segment of proximal duct is noted at 10–11 o'clock position.

  		Figure 3. Benign intraductal papilloma with calcification. Focal dilatation of a solitary duct with intraluminal echogenic debris. Note small focal mass with dense, coarse calcifications in the proximal duct, with ductal obstruction(small arrows).

  		Figure 4. Benign calcified intraductal papilloma with adjacent oil cyst.(a) Small focal mass with coarse, irregular and dense calcifications (small arrows) adjacent to a cystic mass (C). Echogenic floating debris within the cyst with floating fat-fluid level (long arrows). (b) Colour flow studies – focal increase in flow within the mass.

  		Figure 5. Calcified giant intraductal papilloma.(a) Ultrasound and (b) mammography demonstrate a large, bilobed, densely calcified mass with distal shadowing (arrows).

  		Figure 6. Benign intraductal papilloma.(a) Mammography – oblique band like density along inferolateral quadrant of the left breast. (b) Ultrasound – focal dilatation of a solitary duct with an intraluminal mass arising from the ductal wall. (c) Doppler studies – distinct vascular pedicle within the central core with branching vessels arborising within the mass.

  		Figure 7. (a) Mammography – focal well circumscribed dense mass along the retroareolar region of the left breast. (b) Ultrasound – large cystic mass with echogenic debris totally filling the cyst.

  		Figure 8. Mammography. Well circumscribed peripherally calcified lesion within a progressively tapering band-like density extending from the nipple-subareolar region towards the breast parenchyma.

 

Figure 9

  		Figure 9. Intracystic papillary carcinoma. A moderately large cystic mass in the central breast region with large intracystic solid component is present. The mass is attached to the wall by a broad base and shows irregular branching pattern with peripheral fronding.(D – Cystically dilated duct).

  		Figure 11. Benign intraductal papilloma in a cystically dilated duct. Cystically dilated duct with a small focal mass attached to the ductal wall with a narrow base between 10 and 11 o'clock position. A short segment of dilated proximal duct is identified with dependant echogenic debris with layering effect forming a fluid-debris level.
