Coronal (left) and axial (above left) CT with contrast of the abdomen shows a large, simple, fluid-filled structure above the bladder which is arising from the left ovary. Axial CT (below right) obtained more inferiorly shows a second, smaller, fluid-filled structure in the midline between the uterus and rectum which is in close association with the right ovary which is just to the right of the uterus.
