Abstract
|
|
|
|
Polyacrylamide hydrogel (PAAG) was used for breast augmentation from 1997 to 2006 in the regions of Eastern Europe, Russia, Iran, and China. It was assumed that approximately 300,000 women had undergone PAAG injection. Recently, we experienced several cases with PAAG injection-related complications, and two of them had received PAAG injection two years before, after the State Food and Drug Administration of China banned this material in 2006. In this study, we aimed to evaluate the complications and imaging findings of patients with PAAG-injected breast augmentation. Four out of six cases presented suspicious for malignancy findings in imaging work-up. One case was confirmed as invasive ductal cancer in a 25-yearold female. Thorough work-up with multimodal breast imaging and pathologic confirmation with tissue biopsy should be considered in patients with suspicious findings with a history of PAAG injection.
