Nonkomunikan rudimenter uterin hornda ektopik gebelik

The incidence of congenital uterine anomalies among fertile women is reported as 1/200 to 1/600. An unicornuate uterus with a rudimentary horn is the rarest mullerian anomaly and its incidence is 1/100.000. The obstetric complications of mullerian anomalies are ectopic pregnancy, habitual abortion, prematurity and malpresentation. Conception in a noncommunicating rudimentary horn arises from transperitoneal migration of either spermatozoa or the fertilized ovum from the contralateral site. Pregnancy outcome is poor and the most dreaded complication is rupture of the rudimentary horn pregnancy. Treatment options include excision of the rudimentary horn or methotrexate. We present a case of ectopic pregnancy in a noncommunicating rudimentary uterine horn that was unruptured and succesfully treated with excision.
