PURPOSE: To determine whether recent progress in imaging has made it possible to diagnose spontaneous detorsion, which is an accepted concept in the gynecological literature but until now has been a presumptive diagnosis that could not be confirmed because of the lack of imaging proof. MATERIALS AND METHODS: We searched for patients who had a diagnosis of spontaneous detorsion on MRI between January 2000 and January 2003, and selected only patients who met a selection of strict criteria, including mainly enlargement and hyperintensity of ovarian stroma on T2-weighted (T2W) images, clinical findings compatible with torsion and detorsion, and return of the stroma to normal size on follow-up examinations. Other signs of torsion, such as tubal thickening, were appreciated but not mandatory. Clinical follow-up for at least three years was available. RESULTS: Four patients met the study criteria. No stabilizing procedure was performed in the ovaries. One patient recurred and lost her ovary. CONCLUSION: The diagnosis of torsion followed by spontaneous detorsion was made with high probability in a selected number of patients. The clinical management of such patients remains a matter of debate. Laparoscopy with oophoropexy would be useful for young patients in whom close follow-up cannot be achieved.
