Re: Septated Ovarian Cyst
I have had quite a number of ovarian cysts over the past 4 years. They have always gone away on thier own. I did have a septated complex cyst last year, I think it was about the same size as yours, and that also went away. I was a little worried about it, but since all of my cysts have resolved on thier own, my Dr. was not concerned and I had a re-check in 3 months, and it was gone.
I don't know what kind of cyst it would be - I couldn't find much information either. I woulnt' worry to much at this point - 2.5 cm is pretty small - my Dr.doesn't advocate removing them unitl they are larger - 5 cm I think, or if it persists for a long time. Mine have always been gone, or much smaller when I go for a recheck.
Good luck and let us know how it turns out.
