A case report on ruptured rudimentary horn ectopic pregnancy

Unicornuate uterus with noncommunicating rudimentary horn occurs due to incomplete fusion of mullerian ducts. This malformation results from the defective fusion of the duct with the contra-lateral side. This rudimentary horn may or may not have functional cavity. Pregnancy in this horn is a rare phenomenon usually resulting in rupture during second trimester of pregnancy. IT is a rare condition that can lead to a catastrophic outcome when it rupture. Prerupture diagnosis of pregnancy in rudimentary horn with ultrasonography is technically difficult, with sensitivity of 30%. Pregnant rudimentary horn can present with wide range of symptoms that may be similar to ectopic pregnancy or may remain silent with features of normal pregnancy.1-2 We report a case of ruptured non-communicating rudimentary horn at 19 weeks in pregnant lady. In our opinion, routine excision of rudimentary horn should be undertaken during non-pregnant state laparoscopically. However, those women who refuse should be adequately counselled regarding potential complications and if pregnancy occurs in rudimentary horn, first trimester laparoscopic excision should be done.
