Case Discussion

Endometriosis can result in recurrent cyst formation in ovaries, as in this case with T2 shading typical of the recurrent hemorrhage. Ovaries tend to adhere to uterus. Always look for other pelvic endometriotic deposits. They are horrible to have if one has not conceived yet, as they distort the fallopian tubes.
