Presentation
Nipple discharge single duct right breast
Patient Data
Enlarged image of a cystic structure behind the nipple. Note how the lesion tapers up toward the posterior aspect of the nipple.
A large duct diverticulum.
Case Discussion
Galactography is a dying art. It takes time, effort and patience It makes sense only when a single duct is involved. The actual nature of the discharge does not predict the etiology. The traditional teaching that a bloody discharge is more sinister than others is not true in practice.
Bilateral nipple discharges would be more likely due to constitutional causes and most of those are idiopathic.
