Radiology Cases of Paraovarian Cyst

Radiology Cases of Right Paraovarian Cyst and Left Ovarian Cyst

CT of paraovarian cyst and ovarian cyst
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.
