Abstract

Objective: To describe a rare form of ectopic pregnancy and to show the interest of endovaginal ultrasound in its early diagnosis. Method: We report a rare case of a horn pregnancy discovered on ultrasound in a 42-year-old woman. The endovaginal ultrasound examination revealed an empty uterus of normal size with a regular cavity line. We found an ectopic gestational sac at the coronal level (seven weeks of amenorrhea). It was surrounded by a myometrium measuring 5 mm in thickness. There was no intraperitoneal fluid effusion. The diagnosis of cornual pregnancy was made on the ultrasound data, it was confirmed by the BHCG assay (25 215 mUI/ml) and the patient underwent laparoscopy successfully. Conclusion: Endovaginal ultrasound coupled with plasma BHCG assay allows early diagnosis of corneal ectopic pregnancy. Cornual pregnancy is a rare form, and its treatment is based on expulsion of the pregnancy and haemostasis of the uterine horn in case of haemorrhagic rupture. The two techniques for hemostasis of the uterine horn are cornuotomy with suture or resection of the uterine horn with salpingectomy, most often by laparoscopy.
