Suspect Rudimentary Horn Pregnancy in Failed Induction

Abstract

Background: Pregnancy in a rudimentary horn is an extremely rare and life-threatening condition, as it mostly terminates by rupture by the second trimester of pregnancy. This article reports on a case of unruptured rudimentary horn pregnancy for which the diagnosis was initially missed at an 18 weeks' sonogram. Case: A 27-year-old woman, gravida 2, para 1, living 1, was referred to an obstetric unit at 24 weeks of gestation in view of failed induction for intrauterine death. This patient presented with intrauterine death, and abortion induction was attempted with a number of medicines. Induction was not successful; thus, a rudimentary horn pregnancy was suspected. This timely prerupture diagnosis and excision of the rudimentary horn was performed, thus reducing the patient's morbidity and potential mortality. Results: This patient's postoperative period was uneventful. Conclusions: Only 8% of rudimentary horn pregnancies are diagnosed before the symptoms appear. A careful pelvic examination, USG and MRI points towards diagnosis. (J GYNECOL SURG 31:95)
