A 48-year-old female with complications related to polyacrylamide gel augmentation mammoplasty.. A. Mediolateral oblique mammography view of both breasts shows multiple conglomerated, well-circumscribed equal density masses at the upper breasts.. B. Ultrasonography reveals multiple anechoic or complex solid and cystic masses at the upper outer quadrants of both breasts. Several masses at the upper quadrant of the left breast show internal echogenicity without vascularity on color Doppler ultrasound.

Mammography (MMG) showed multiple conglomerated, well-circumscribed, equal density masses in the upper outer quadrants of both breasts (Fig. 1A). Several masses in the upper quadrant of the left breast showed anechoic and complex solid masses and cystic masses without vascularity on Doppler ultrasound (Fig. 1B).

A 48-year-old female with complications related to polyacrylamide gel augmentation mammoplasty.. US reveals a large amount of fluid collection with internal debris in the retropectoral space of the right breast, suggesting an infection in the polyacrylamide gel collection. On the contralateral side, US shows a smaller amount of polyacrylamide gel collection without echogenic debris. Color Doppler imaging shows mildly increased peripheral vascularity.. US = ultrasonography

On the contralateral side, a smaller amount of PAAG had collected without echogenic debris (Fig. 2).

A 53-year-old female with complications related to polyacrylamide gel augmentation mammoplasty.. A. Mediolateral oblique view of the mammography shows multiple round- or oval-shaped equal density masses with calcifications in both breasts.. B. Ultrasonography shows multiple complex solid and cystic masses and heterogeneous echoic lesions with calcifications (arrows) in both breasts.. C. Chest CT angiogram shows multiple low attenuated cystic lesions in both chest walls, surrounding and intervening into the pectoralis muscles, suggesting an incomplete removal of the polyacrylamide gel.

MMG showed multiple round- or oval-shaped equal density masses with calcifications in both breasts (Fig. 3A). On US, there were multiple complex solid and cystic masses and heterogeneous echoic lesions with calcifications in both breasts (Fig. 3B). CT angiogram of the chest. Chest CT angiogram showed multiple low attenuated cystic lesions in both chest walls, surrounding and intervening into the pectoralis muscles, suggesting incomplete removal of the PAAG (Fig. 3C).

A 50-year-old female with complications related to polyacrylamide gel augmentation mammoplasty.. A. Mediolateral oblique view of the mammography. Multiple equal density masses are replacing both breasts.. B. Ultrasonography shows multiple variable-sized anechoic, complex solid, and cystic or heterogeneous echoic masses in both breast parenchyma, retromammary area, and interpectoral space.. C. Fat-saturated T2WI shows high signal intensity lesions, suggesting a large amount of fluid collections in the intramammary, retromammary, and interpectoral spaces. Contrast-enhanced subtraction T1WI did not show abnormal enhancing lesions that suggest a breast cancer.. T1WI = T1-weighted image, T2WI = T2-weighted image

MMG showed multiple equal-density masses having replaced both breasts, and breast parenchyma and masses could not be clearly distinguished on MMG (Fig. 4A). US also showed multiple variable-sized anechoic, complex solid, cystic, or heterogeneous echoic masses in the parenchyma of both breasts, retromammary area, and interpectoral space (Fig. 4B). Contrast-enhanced subtraction T1WI did not show abnormal enhancing lesions, suggesting breast cancer (Fig. 4C).
