Teenager after a motor vehicle accident

CT of ovarian cyst
Axial CT with contrast of the pelvis shows a distended contrast-filled bladder in the center of the image and contrast in the distal left ureter adjacent to the normal left ovary and contrast in the distal right ureter adjacent to the right ovary which contains a round low density lesion in its center. There is also a small amount of physiologic free fluid in the pelvis

The diagnosis was right ovarian cyst.
