Unilateral autoinflation of a saline-filled breast implant initially diagnosed as capsular contracture: a case report and review of the literature

Spontaneous inflation of saline breast implants is a rare phenomenon. In this case report, we share our experience treating a patient who complained of asymmetric breasts from what appeared to be a straightforward case of capsular contracture. Spontaneous autoinflation of the right breast implant was subsequently found to be the cause of breast asymmetry and hardness. The presentation, diagnostic challenge, management, and mechanism of this rare phenomenon are presented here.
