[Torsion of the ovary in children: value of echography and difficulties of anatomical interpretation].

Two cases with the clinical presentation of peritonitis and a 9 year-old girl with ovarian torsion are reported: a 2 year-old girl with paroxistic abdominal pain and occlusive syndrome. Ultrasonography was of main interest in that situation. The necrotized ovary was extracted at intervention in both cases; histological data did not allow to distinguish the torsion on an hemangiomatous ovary from the torsion of an healthy ovary, which represents an exceptional feature.
