Abstract

Torsion of the normal adnexa usually occurs in first decade of life and is less common then torsion of an ovary containing a mass. It is thought to be related to the particular mobility of the pediatric adnexa, which allows twisting at mesosalpinx as a result of change in intraabdominal pressure or in body position.1 50% of patients have a history of pain with spontaneous recovery.2,3 Although torsion may occur with normal ovaries, most reported cases have involved children with ovarian masses, or in women younger then 30 years of age. There is a rotation of the ovary or adnexa about the ovarian pedicle, causing lymphatic obstruction followed by venous then arterial obstruction.
