Figure 3. (A) Computed tomography of the abdomen and pelvis. In the pelvis, a midline complex and mostly cystic lesion is indicated by the yellow arrow. Septations and soft tissue components were noted of the lesion that is 25 cm in approximate diameter and appears to arise from the left ovary. The uterus is grossly unremarkable but somewhat distorted in appearance. The right ovary was not seen. The left and right colon is compressed but otherwise unremarkable. The appendix is unremarkable. The urinary bladder is not distended or inflamed. There are no hernias. (B) The green circle encloses the left hydronephrosis of the left kidney.
