WHILE acute abdominal symptoms are not infrequently due to torsion of an ovarian cyst, such symptoms from spontaneous torsion of the pedicle of a normal ovary are rare. Downer and Brines,3in 1931, collected 18 cases from the literature which they considered to be true examples of torsion of the normal ovary. They included only children and young unmarried girls, in order to exclude the possibility of inflammatory disease of the adnexa as a possible predisposing cause of torsion. Their patients ranged in age from 4 months to 16 years. In addition, they reported a case of their own in a 7-year-old girl. Baron1also reported an instance of torsion of a normal ovary in a 7-year-old girl, and, later, torsion and infarction in the remaining ovary of the same child.2Another example occurring in a 7-year-old child was briefly reported by Smith4in 1950.
