The importance of ultrasound examination in the diagnosis of a rare form of molar pregnancy: a case report

İntroduction

A cornual pregnancy is a rare type of ectopic pregnancy which occurs when the fertilised egg implants in that part of the fallopian tube buried deep in the wall of the uterus. Hydatidiform mole ( molar pregnancy) is a rare mass or growth. Molar cornual ectopic pregnancy is extremely rare.

Objective

The aim of this work is to describe a rare form of molar cornual pregnancy and show the importance of ultrasound examination in its diagnosis.

Method

In this study, we present a case of molar cornual pregnancy diagnosed by ultrasound examination, serial serum beta subunit of human chorionic gonadotropin and diagnostic laparoscopy.
a 32 year -old woman with an antecedent of asthma, attented our department of Obstetrics and Gynecology at Ben Arous Hospital (tunisia) for ultrasound examination at 8 weeks of amenorrhea. The ultrasound examination was performed by suprapubic and endovaginal approach.

Results

At the ultrasound examination the uterus was empty and We demonstrated an ectopic gestational sac embryonated of 0.96 cm cranio caudal length (that is to say 7 weeks of amenorrhea). The sac was surrounded by placenta, Which was enlarged and contains areas of multiple, diffuse anechoic lesions. The diagnosis of cornual pregnancy was made from data of the ultrasound examination. It was confirmed by the βHCG (85843.4mUI/ml), diagnostic laparoscopy and Pathologic analysis ( placental tissue with features consistent with a partial molar pregnancy). the patient had a successful laparotomy.

Conclusion

Molar cornual pregnancy occurs rarely. Its diagnosis is not often made.Its discovery is made frequently at the rupture stage. Endovaginal ultrasound examination helps discover cornual pregnancy at an early stage.
