cornual ectopic pregnancy

Cornual ectopic pregnancies are rare and represent a gestational sac within the cornua of a bicornuate or septate uterus.

Terminology

Although sometimes interchangeably used with interstitial pregnancy, cornual pregnancy specifically refers to the presence of a gestational sac within a rudimentary uterine horn, a unicornuate uterus, cornua of a bicornuate uterus or septate uterus.

Epidemiology

They are reported to represent less than 1% of all ectopic pregnancies .

Radiographic features

Ultrasound

• interstitial line sign
• eccentric position of sac: gestational sac is surrounded by a thin rim (<5 mm) of myometrium and is more than 1 cm from the lateral wall of the endometrial cavity 

Treatment and prognosis

Rupture of a cornual pregnancy can cause a catastrophic intra-abdominal bleed.
