The probability: of the MRI mass being cancerous depends on a number of MRI features, including the shape and borders of the mass, and the way it enhances after the contrast injection. So there is not enough information to make an assessment . The fact that it wasn't seen on U/S doesn't make much difference. The cyst is benign. What is the BIRADS code at the end of the report? That gives the level of suspicion

Probably low: It sounds like the findings are the same finding. But it is better to be safe and see that they are one and the same thing. MRI is very sensitive so it may see something the other tests didn't. So it is better to see what the surgeon says. Don't be surprised if he wants it out to be certain what it is . Good luck
