Endometriosis is a chronic inflammatory condition defined by endometrial stroma and glands found outside of the uterine cavity. The most common sites affected are the pelvic peritoneum and ovaries.

May present incidentally in asymptomatic women, or more commonly in women of reproductive age who complain of chronic pelvic pain and/or sub-fertility.

M. Jonathon Solnik, Professor of Obstetrics, Gynaecology and Medical Imaging by Cross-Appointment, Temerty School of Medicine at the University of Toronto, gives us an overview of diagnosis and management of the condition.
