Galactography is an excellent tool for delineating and locating the cause of nipple discharge. The conventional approach involves cannulation of the secreting duct, followed by injection of contrast. However, it is sometimes difficult to identify the discharging duct due to intermittent discharge that has subsided at galactography. Inverted nipple is another obstacle, rendering identification of the discharging ductal orifice difficult and sometimes impossible. Under these circumstances, ultrasound-guided percutaneous galactography becomes a valuable alternative method for evaluating women with a non-lactational nipple discharge.
