On 3D transvaginal ultrasound, the uterine septum had a 2 cm deep indentation with an angle of 65  (Figure 1).
Hysterosalpingogram demonstrating two uterine cavities with patent fallopian tubes. It is not possible to differentiate between a septate uterus and a bicornuate uterus from this image because the presence or absence of a fundal indentation cannot be observed.
