Background:
Early diagnosis of ovarian torsion can help prevent irreversible damage to the adnexal structures in women desiring to maintain fertility.
Case:
The patient was transferred by ambulance for a six-hour history of severe lower abdominal pain. Magnetic resonance imaging (MRI) revealed bilateral enlarged ovaries measuring 5 x 6 cm (right) and 4 x 5 cm (left) with a right twisted and thickened peduncle. Ultrasonography failed to detect the peduncle changes. At surgery, the right adnexa was twisted 180 degrees in a clockwise direction with no findings suggestive of gangrenous change, hemorrhagic infarction or ischemic change. Detorsion of the twisted ovary was performed.
Conclusion:
Detection of tube torsion at MRI may be useful in the preoperative evaluation for surgical detorsion of twisted adnexa encountered in enlarged ovaries.
