Abnormal breast implant on Xray - what could this be?

The dark area could be an air pocket. In any case it is best to visit with your surgeon or another board certified plastic surgeon for an evaluation. A mammogram or ultrasound may be suggested to help identify the area in question.

I would suggest getting a mammogram with an ultrasound if needed to see if this is breast tissue or just the implant. Most implants do not look like this.

The darker area appears to be a fluid level. I’m not sure whether you have silicone implants or saline implants. If you have saline implants, my question would be whether that one was completely filled or it had a bit of air in it at the time of filling. If you have silicone implants, I don’t understand why there would be a fluid level in your silicon implant and I wonder whether this is a fluid level of either your stomach or your intestine which is super imposed over your breast implant. Follow up with your plastic surgeon.
