Depending on the symptoms, the differential diagnosis will change. In patients with chronic abdominal pain, diagnoses such as chronic pelvic inflammatory disease, pelvic adhe-sions, gastrointestinal dysfunction, and other etiologies of chronic pelvic pain should be considered. In patients with dysmenorrhea, both primary dysmenorrhea and secondary dysmenorrhea should be considered. In patients with dys-pareunia, differential diagnoses include chronic pelvic inflammatory disease, ovarian cysts, and symptomatic uter-ine retroversion. Sudden abdominal pain may be caused by a ruptured endometrioma as well as by ectopic pregnancy, acute pelvic inflammatory disease, adnexal torsion, and rupture of a corpus luteum cyst or ovarian neoplasm.
