Four Cases with Congenital Unilateral Absence of Ovary and Fallopian Tube: Review of the Literature

We present four rare cases of congenital unilateral tubal and ovarian absence that were diagnosed in and admitted to the Etlik Zubeyde Hanim Women%u2019s Health Teaching and Research Hospital. The patients were a 23-year-old female with an adnexal mass, a 21-year-old female with chronic pelvic pain with an adnexal mass, a 25-year-old female with an adnexal mass, and a 36-year-old female with primary infertility for 18 months. All patients were evaluated by laparoscopy. The cases showed complete tubal and ovarian absence with a contralateral adnexal mass. The absence of one ovary and tube may be explained by three possible etiopathogenic causes: asymptomatic adnexial torsion that leads to necrosis and resorption, vascular problems, or congenital malformation
