Galactography

Galactography, also known as ductography, is a medical imaging technique used to evaluate the mammary ducts of the breast. This procedure is particularly useful in diagnosing the cause of abnormal nipple discharge, which can be a symptom of various breast conditions, including intraductal papilloma, ductal carcinoma in situ (DCIS), and other benign or malignant lesions.

Procedure

The galactography procedure involves the injection of a contrast medium into the mammary ducts through the nipple. This is typically done using a fine cannula or catheter. Once the contrast medium is injected, mammography is performed to obtain detailed images of the ductal structures. These images help in identifying any abnormalities within the ducts.

Indications

Galactography is primarily indicated for patients who present with:

• Unilateral or bilateral nipple discharge
• Bloody or serous discharge
• Persistent discharge not associated with lactation

Contraindications

Contraindications for galactography include:

• Active mastitis or breast infection
• Known allergy to contrast media
• Pregnancy

Interpretation of Results

The images obtained from galactography can reveal various ductal abnormalities, such as:

• Duct ectasia: Dilation of the ducts, often associated with benign conditions.
• Intraductal papilloma: A benign tumor that can cause nipple discharge.
• Ductal carcinoma in situ (DCIS): A non-invasive form of breast cancer confined to the ducts.

Risks and Complications

While galactography is generally safe, potential risks and complications include:

• Discomfort or pain during the procedure
• Infection
• Allergic reaction to the contrast medium
• Ductal injury or perforation

Alternatives

Other diagnostic methods that may be used in conjunction with or as alternatives to galactography include:

• Ultrasound
• Magnetic resonance imaging (MRI)
• Biopsy
