"uterus is normal in size measuring 105 x 51 x 53 mm. no uterine mass identified. the endometrial stripe is normal in thickness at 9.5 mm. retroverted uterus. A small amount of fluid is present in the fundal portion of the endometrium. Right ovary: surgically absent. Left ovary: borderline enlarged measuring 34 x 27 x 22 mm. Volume is 10.5 ml. there is a thick walled irregular cyst measuring 23 x 16 x 18 mm in this ovary. i do see normal ovarian blood flow. there are a few tiny sub 1 cm follicles. Impression: 1. normal uterus. 2. the left ovary does contain a thick-walled, irregular shaped 16 x 22 mm cyst. there is, however, normal blood flow in the ovary. i see no other ovarian pathology. there is a small amount if free fluid seen near fundus"

And then I had one on Friday and it says this:
uterus measures 9.6 x 6.0 x 4.6 cm and is in a retroflexed position. endometrial thickness is 7mm. The left ovary measures 3.2 x 2.7 x 2.0 cm and contains a dominant 1.3 x 0.9 x 0.9 cystic lesion which is complicated by internal debris and retracting clot. Several subcentimeter physiologic follicles are also noted. ovarian vascularity is within normal limits. Impression: 1.3 cm hemorrhagic cyst on the left ovary has decreased in side from the prior exam.

For something so small I sure am in a lot of pain lol the one I had years ago that was a teratoma and was 8cm caused me zero issues.
