The study of disease transmission in general, innate uterine abnormalities happen in ~1.5% of females (run 0.1-3%). Bicornuate uteri are thought to speak to ~25% (territory 10-39%) of Mullerian conduit inconsistencies.


Bicornuate unicollis uterus, Gestation, Bicornuate bicollis uterus, Ultrasound, USG pelvis


A Bicornuate uterus is a sort of uterine duplication inconsistency. It tends to be delegated a class IV Mullerian conduit anomaly. A Bicornuate uterus is a typical kind of innate uterine inconsistency, and it conveys an expanded danger of barrenness and unnatural birth cycle [1-5].


A bicornuate uterus results from a strange improvement of the paramesonephric channels. There is a halfway disappointment of combination of the pipes, bringing about an uterus isolated into two horns.


Bicornuate uterus is separated by the inclusion of the cervical channel (Figure 1):


Figure 1. Subtypes.

Bicornuate bicollis: two cervical waterways; focal myometrium stretches out to outside cervical os.

Bicornuate unicollis: one cervical waterway; focal myometrium stretches out to inner cervical os.

Radiographic features


The favored techniques for imaging uterine oddities are ultrasound, hysterosalpingogramor MRI. The outside uterine form is sunken or heart-molded, and the uterine horns are broadly disparate. The fundal split is ordinarily more than 1cm profound and the intercornual separation is extended. The uterus is viewed as involving caudally melded symmetric uterine holes with some level of correspondence between the two depressions (generally at the uterine isthmus). Despite the fact that not a particular finding, the edge between the horns of the bicornuate uterus is typically more than 105°3.


HSG could not be done since patient was pregnant.


USG pelvis uncovered endometrium in the district of collection of uterus bifurcating cranially into two horns with interceding tissue reliable with typical myometrium. Single gestational sac with a fetal shaft of 12 weeks gestational age was available in the left horn and endometrial response was noted in the privilege horn. Fetal heart action was seen (Figure 2).

May help affirm life structures by demonstrating a profound (>1 cm) fundal separated in the external uterine shape and an intercornual separation of >4 cm. The uterus exhibits typical uterine zonal anatomy. MRI imaging uncovered a bicornuate uterus with gestation in the left horn and endometrial reaction in the right horn (Figure 3).

Treatment and prognosis

Careful intercession is typically not demonstrated without conceptive troubles. In ladies with a background marked by intermittent pregnancy misfortune and in whom no other barrenness issues have been recognized a Strassman metroplasty can be considered.

Differential analysis

Uterus didelphys: Complete disappointment of combination happens during the improvement of the paramesonephric conduits with duplication of the uterus, cervix and vagina Septate uterus 12: has an ordinary fundal shape however is portrayed by a constant longitudinal septum that in part partitions the uterine depression.


Congenital uterine anomalies have been clearly implicated in women suffering with recurrent miscarriage. In women with infertility the role of these anomalies remains unclear. Correct assessment of prevalence of these anomalies in women with recurrent miscarriage and infertility will play a major role in the treatment. My case report is regarding a 20 yr old female having Bicornuate unicollis uterus with 12 weeks gestation. It was a natural conception after 2 years of married life. The ultrasound findings were normal for the gestational age. The gestation was in left horn of uterus with endometrial reaction in the right horn. I could not find any abnormalities in the ovaries.


Though Ultrasound is the primary investigation which is easily available, cheap and nonradiation to screen and detect uterine anomalies, Magnetic Resonance Imaging is more specific and sensitive for detection of Septate Uterus than Ultrasound.
