Interesting info
I found this on Medcyclopaedia. Interesting what it says about mimicing solid masses.
Corpus luteum cyst
After ovulation, the dominant follicle collapses and becomes deflated, with an irregular crenulated wall. The cells lining the follicle proliferate and with invasion by thin-walled capillaries, the cells secrete progesterone, forming the corpus luteum.
At ultrasound, the fresh corpus luteum usually appears as a hypoechoic structure with an irregular wall and may contain some internal echoes corresponding to haemorrhage. As the corpus luteum develops, some 48 days after ovulation it appears as an echogenic area approximately 15 mm in size. However, the corpus luteum varies markedly in size and echo texture. Haemorrhage within the corpus luteum may simulate a solid or complex mass. Duplex Doppler demonstrates persistent and prominent diastolic flows surrounding the corpus luteum throughout the luteal phase of the menstrual cycle. MRI also clearly shows the cyst (Fig.1) (Fig.2).
Free fluid in the cul-de-sac is evidence of ovulation, particularly when a previously seen follicle has collapsed. However, the amount of fluid observed within the cul-de-sac significantly exceeds the amount of fluid actually released by follicular rupture. Also, anovulatory women may demonstrate levels similar to those of peritoneal fluid as ovulating women. This supports the hypothesis that peritoneal fluid is formed predominantly by hormonally stimulated secretions from the ovary and not from the follicular fluid itself.

I currently am having problems with cysts and alot of fluid in my oelvis, I am not getting much info from the ultrasound Dr. , or my gyno/ono at this time I am scheduled for my fourth ultrasound since nov 05 and hopefully will find out next week if surgery is a must.
