Rupture of Non-communicating Rudimentary Horn of Uterus at 12 Weeks' Gestation

The rudimentary horn of uterus is an extremely rare malformation and potentially serious obstetric entity, threatening maternal and fetal outcome. Diagnostic sonography of early pregnancy in a non-communicating rudimentary horn is difficult but important. We report a case of ruptured non-communicating rudimentary horn with unicornuate uterus at 12 weeks’ gestation, where diagnosis is made before surgery. Excision of the rudimentary horn and ipsilateral salpingectomy (to prevent a further ectopic tubal gestation), conserving the ovary, is the recommended surgical procedure for patients desiring to maintain their fertility potential. The subsequent obstetric prognosis is reassuring. Diagnostic imaging examinations of the reproductive system after this treatment showed no negative effect from surgery on subsequent fertility and there was no reported case of uterine rupture during subsequent pregnancy in the remaining unicornuate uterus after rudimentary horn excision. Future pregnancies will require extremely close monitoring and a caesarean section is highly recommended.

[Rudimentary horn pregnancy diagnostic: difficulties and therapeutic management]

The occurrence of rudimentary horn pregnancy is an extremely rare and potentially serious obstetric entity, threatening maternal and fetal outcome. The authors report five cases of rudimentary horn pregnancy, the difficulties in making a proper diagnosis and the therapeutic management of this pathological entity, stressing the importance of transvaginal ultrasound, of pelvic MRI and laparoscopy in the early diagnosis of this type of uterine malformation.

An unusual case of cervical diverticulum identified by presence of 3 cavities at diagnostic hysteroscopy

Herein is presented the case report of a patient who had severe dysmenorrhea since menarche, known right unicornuate uterus with a left rudimentary horn, and recurrent hematometra. Previous hysteroscopic drainage of the hematometra temporarily alleviated the symptoms. At subsequent hysteroscopy, 3 cavities were identified, 2 corresponding to the uterine horns and the other to a cervical diverticulum. Hysteroscopic metroplasty with drainage of the rudimentary horn hematometra provided long-term relief of the symptoms. The diagnosis was verified at diagnostic laparoscopy.

[Recurrence of a rudimentary uterine horn rupture at 25 weeks of gestation: a case report]

Pregnancy in a rudimentary uterine horn is a rare event which can be revealed by uterine rupture. Following the fetal extraction, some authors recommend the ablation of the rudimentary horn, in order to limit the risk of uterine rupture in case of subsequent pregnancy in the same horn. We report the obstetrical outcome of a patient with a history of rudimentary uterine horn rupture the treatment of which was conservative.
