Retromammary fluid collection as a late complication of breast implants: magnetic resonance imaging findings.

Imaging examinations, particularly magnetic resonance imaging (MRI), play an important role in the diagnosis of breast implant complications. Two cases of retroprosthetic serous-like fluid collection, an unusual late complication that has not been described previously in the literature, are presented. It is important for radiologists to know the MRI findings of this complication, which suggest the correct diagnosis, avoiding unnecessary additional procedures.
