Advanced endometriosis: A diagnostic dilemma

Endometriosis is a debilitating medical condition in females in which endometrial glands and stroma appear and flourish in areas outside the uterine cavity and walls, most commonly in the ovaries. Incidence in general population is 5-15% and around 30% in infertile women. Usual age group is 20-30years and patients present with dysmenorrhoea, dyspareunia, dyschezia, infertility and pelvic pain. We report two interesting cases of stage IV endometriosis who presented as bilateral complex ovarian masses which simulated ovarian cancer on ultrasound. MRI pelvis for both these cases diagnosed stage IV Endometriosis.
