Patient Data

Age: 53 years
Gender: Female

4 cm cyst with inside many hyperechoic bright spots.


Polycyclic radiopaque mass with well-defined borders in the right breast


Macrolane gel aspirated using a 18G needle on a 60 mL syringe.

Case Discussion

Six months before, the patient underwent breast augmentation with Macrolane gel injections.

Macrolane is a biocompatible, soft-tissue filler of hyaluronic acid of non-animal origin (manufactured by Q-Med, Uppsala, Sweden).

The cyst was aspirated using an 18G needle on a 60 mL syringe. The procedure was repeated because the gel obstructed the lumen of the needle. In total about 25 cc Macrolane gel was aspirated. The procedure, performed without local anesthesia, was well tolerated and the cyst disappeared clinically, although ultrasound showed a persistent 1 cm cyst.

Accordingly a French prohibition of the use of Macrolane in aesthetic breast augmentation for reasons similar to criticisms of autologous fat grafting, in 2012 Q-Med, the manufacturer of Macrolane, has decided to discontinue the promotion of Macrolane for breast augmentation until further notice.
