Although torsion may rarely occur in normal adnexa, it more frequently arises from one of many anatomic changes. Torsion of a normal ovary is most common among young children, in whom developmental abnormalities (eg, excessively long fallopian tubes or absent mesosalpinx) may be responsible. In fact, fewer than half of ovarian torsion cases in pediatric patients involve cysts, teratomas, or other masses.
