Abstract

Asymptomatic unilateral absence of a portion of a fallopian tube with or without adjacent ovarian agenesis is a very rare condition. The true incidence is unknown. Two etiologic causes are possible. Asymptomatic segmental torsion of the uterine tube and ovarian pedicle may occur for certain reasons during adulthood, in childhood, or even during the fetal stages. Consequently, torsion may give rise to necrosis and autoamputation. Alternatively, the absence of these organs may be congenital. Ovarian pregnancy is a rare form of ectopic pregnancy occurring in 0.5~1% of all ectopic pregnancies. Moreover, ovarian pregnancy in patient with congenital unilateral tubal and ovarian agenesis has not been reported. But, the presenting symptom is very similar and difficult to distinguish with other forms of ectopic pregnancy. Early detection is important role in preserving fertility to avoid the ablation of functional ovarian tissue. We report a case of congenital unilateral tubal and ovarian agenesis diagnosed during laparoscopic treatment of ovarian pregnancy.
