Torsion of the normal uterine adnexa in premenarchal girls.

Two cases are reported of torsion of the normal uterine adnexa in premenarchal girls. In one patient, aged 3 yr, both the ovary and fallopian tube had undergone torsion. The second patient, aged 11 yr, had sustained torsion of the fallopian tube alone. This is the first reported case of torsion of the fallopian tube occurring without torsion of the ovary in a patient in this age group. The mechanisms of torsion of normal uterine adnexa are described and the operative management is discussed.
