Abstract
Endometriosis is a common condition that occurs in 6-10% of all reproductive age women. This number increases to approximately 40% in women with infertility and nearly 75% in women with complaints of chronic pelvic pain. Endometriosis is characterized by the presence of endometrial glands and stroma outside the uterine cavity. The most common complaints associated with endometriosis are dysmenorrhea and pelvic pain; however, patients often present with a variety of symptoms and on occasion are asymptomatic. When presenting with haemorrhagic ascites, endometriosis mimics ovarian malignancy. Conservative medical treatment is a feasible management option, especially in young patients who desire to preserve fertility. This article aims to present an extremely rare presentation of endometriosis, haemorrhagic ascites, and a review of the associated literature.
