Introduction
Cornual pregnancy is rare, accounting for approximately 2-4% of all
ectopic pregnancies [1]. By definition, it refers to the
implantation and development of a gestational sac at the proximal and
lateral regions of the uterus (aka uterine horns or cornua). As with the
majority of other types of ectopic pregnancy, cornual pregnancy
diagnosis is based on clinical suspicion, β-hCG measurements and
transvaginal ultrasound findings [2]. As with other types of ectopic
pregnancy, cornual pregnancy is associated with severe patient morbidity
and mortality [3]. Therefore, timely and accurate diagnosis is key
as it directly affects treatment type and urgency. Several management
options are available from the conservative (methotrexate administration
and expectant management) up to the more radical side of the spectrum
(cornuotomy, cornual resection, hysterectomy) [4]. Hysteroscopy is
an additional option that combines effective and complete removal of the
gestational sac, without severely affecting uterine anatomy, however its
application usually requires imaging guidance [5].
In this report, we present the case of a cornual ectopic pregnancy,
which could not be diagnosed via traditional ultrasonographic imaging
and instead was verified by MRI imaging. Subsequently, guided by the MRI
imaging data, hysteroscopic resection and removal of all products of
gestation was safely and successfully performed without any
complications and with the patient making a swift recovery.
