<unk>  is the rotation of the ovary and portion of the fallopian tube on the supplying vascular pedicle
Referred to as adnexal torsion and tubo-ovarian torsion
Occurs in females of all ages
Most common in reproductive age adults
In children, it is most common in 9-14 years of age
Risk factors:<unk>  mass
Fertility treatments<unk>  cysts (usually > 4 cm) and neoplasms account for 94% of cases in adults
Torsion more common on the right, as the sigmoid colon tends to stabilize the left
In children, hypermobility of the ovary many be the primary cause of torsion
Dual blood supply from<unk>  and uterine arteries
Most common in reproductive age adults

Torsion occurs from either of two causes:
Cysts greater than 4 cm are more likely to torse
Absence of<unk>  Doppler flow is highly specific for torsion, but normal Doppler flow does not completely exclude torsion
Ovarian torsion
Appendicitis
Testicular torsion
Perforated appendicitis
Tubo-ovarian abscess
Peritonitis
Epididymitis
Abdominal aortic aneurysm
