Female teenager with abdominal pain

CT of uterus didelphys or bicornuate uterus
Sequential axial CT with contrast of the abdomen shows a fluid-filled bladder in the anterior aspect of the pelvis that has a soft tissue structure posterior to it, believed to be the uterus, that is composed of what appear to be left and right horns.

The diagnosis was Mullerian duct anomaly in the form of a uterus didelphys or a bicornuate uterus.
