"A divided uterus can be seen on hysterosalpingogram (HSG), but it is difficult to differentiate between septate and bicornuate anomalies since the uterine fundal contour is not visible 5. Accuracy of hysterosalpingogram alone is only 55% in differentiation between both entities. An angle of less than 75° between the uterine horns is suggestive of a septate uterus while an angle of more than 105° is more consistent with a bicornuate uterus."

"A bicornuate uterus results from abnormal development of the paramesonephric ducts. There is a partial failure of fusion of the ducts, resulting in a uterus divided into two horns."
"bicornuate bicollis: two cervical canals; central myometrium extends to the external cervical os"
"bicornuate unicollis: one cervical canal; central myometrium extends to the internal cervical os"
"The preferred methods of imaging uterine anomalies are ultrasound, hysterosalpingogram or MRI. The external uterine contour is concave or heart-shaped, and the uterine horns are widely divergent. The fundal cleft is typically more than 1 cm deep and the intercornual distance is widened."
"uterus didelphys: complete failure of fusion occurs during the development of the paramesonephric ducts with duplication of the uterus, cervix and vagina"
