Type: Educational Exhibit
Area of Interest: Breast
Imaging Techniques: Ultrasound, MR, Mammography
Procedure: Galactography
Special Focus: Neoplasia

Learning objectives:
- Describe clinical and pathologic aspects of intraductal papilloma of the breast; - Present the most relevant radiologic aspects in mammography, ultrasonography and magnetic resonance imaging (MRI); - Report the main differential diagnosis in the different imaging methods.
Background:
INTRODUCTION The intraductal papilloma it's a benign neoplasm of the breast; Most frequently diagnosed at the end of reproductive life, between the 5th and 6th decades; Unilateral in about 80% of the cases. When the papilloma is subareolar, it's called "central papilloma". Beyond of this region, th[...]
Findings and procedure details:
Mammogram aspects Well-defined retroareolar oval mass; Retroareolar oval, punctate or amorphous calcifications Dilated duct. In Galactography, the most common aspect is a intraluminal filling defect, usually with an abrupt "cutoff". Ultrasonographic aspects Solid masses accompanied by ductal [...]
Conclusion:
Intraductal papilloma, despite being a benign neoplasm with characteristic radiological features, it's a pathology that requires a histopathological diagnosis, considering that its main differential diagnoses such as papillary carcinoma and invasive ductal carcinoma in many situations present simila[...]
