Evaluation of MRI findings after polyacrylamide gel injection for breast augmentation.

OBJECTIVE: Polyacrylamide gel injection mammoplasty has recently been used for breast augmentation. However, many complications have been reported including complications that in some patients resulted in the need for mastectomy. This article reviews the MRI appearances of various complications of polyacrylamide gel injection mammoplasty including breast asymmetry; intramammary or extramammary gel displacement, including intrathoracic extension; and glandular atrophy, inflammation, and infection resulting in mastectomy. CONCLUSION: Because poly acrylamide gel has a high water content, we found that sagittal and axial T2-weighted are the best sequences to use to detect complications.
