Myometrium shows a small anterior body intramural myoma measuring 5.8 mm. please explain that to me. that's y result of my endovaginal ultrasound?

Tiny: This myoma is tiny. Unless you were having problems with infertility or with abnormally heavy vaginal bleeding, this wouldn't typically be operated on. A lot of women have fibroids and don't know because they aren't affecting anything adversely. If you are having infertility or bleeding issues then your doctor may recommend removal, but highly unlikely, especialky given it's intramural.

Fibroid: A myoma is also called a fibroid tumor. They're very common, especially during the 30's and 40's. Usually they require no treatment unless they cause problems, such as abnormal bleeding. A small one like yours in the wall of the uterus (intramural) is unlikely to cause any problem.
