Purpose
Ovarian torsion is serious cause of lower abdominal pain and is the gynecologic surgical emergency.
Ovarian torsion is an uncommon,
estimated as the cause of 2.7% of gynecologic emergencies in the United states.
An early and accurate diagnosis is important for fertility preservation.
In addition,
if the ovarian torsion is complete and is not diagnosed and untreated,
hemorrhagic infarction can occur and may lead to peritonitis and death.
The clinical presentation is nonspecific and can mimic other diseases of acute abdominal pain.
Imaging therefore plays a central diagnostic role.
Although ultrasonography (US) have been reported to be useful in detecting ovarian torsion,
computed tomography (CT) and magnetic resonance imaging (MRI) may also be useful in making the preoperative diagnosis of ovarian torsion.
An accurate diagnosis and differentiation of hemorrhagic from nonhemorrhagic infarction is important for treatment planning.
The goal is to identify new findings and to discuss the relation of established findings.
