Hi and welcome to HCM.
YOu shouldnt be worried. This is common finding in women and usually dont cause any symptoms. This ovarian adjacent looks like dilated fallopian tube
or benign follicular cyst
. Heterogenous myometrial myxture is nonspecific finding which usually suggest some kind of mioma formation but this is very operator dependent test. This is benign tumour which makes problem if become large enough. I suggest just to do frequent check ups. Wish you good health.
