Fig. 9.15. Torsion of a paraovarian cyst. In a 14-year-old girl with severe acute pelvic pain a cystic lesion was found on sonography. CT shows normal ovaries in the ovarian fossa and a 7-cm cystic lesion (asterisk) in the cul-de-sac. The latter shows mild wall thickening at its left contour. Exploratory laparotomy found torsion of a right paraovarian cyst with involvement of the right fallopian tube. The ovaries were unremarkable...
