Discussion of Nipple inversion
- When nipple abnormalities such as inversion are identified, it is important for the technologist to document them in the medical record so that the radiologist will be aware of the findings and the relevant medical history.
- Nipple inversion may be bilateral or unilateral and usually results from a benign process that takes place gradually, over a long period.
- When nipple inversion occurs more rapidly (eg, within a few months), the cause is more likely to be a malignancy.
- Additional mammographic work-up is needed in cases in which the history of nipple inversion is not known or in which nipple inversion developed over a short period of time.
- The additional work-up should include spot compression views with the nipple in profile (to determine whether there is a retroareolar mass) as well as craniocaudal and lateral spot magnification views to assess microcalcifications.
- If the mammographic views are unrevealing, US should be performed.
- Reported histopathologic findings in cases of acute nipple inversion with a benign cause include mammary duct ectasia, postsurgical changes, fat necrosis, fibrocystic changes, and Mondor's disease.
