We investigated whether this process can be characterized by sonographic features.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>Twelve menstrually cycling women with 14 separate episodes of laparoscopic\u2010proven torsion of normal adnexa were identified retrospectively, and the results of their preoperative gray\u2010scale ultrasound examinations and Doppler flow evaluations were analyzed. The cases were classified into \u2018short\u2010term\u2019 (&lt; 24 h; range, 3\u201324 h) and \u2018prolonged\u2019 (&gt; 24 h; range, 1\u201310 days) duration of torsion according to the reported period of abdominal pain before admission. Absence of any additional adnexal pathology was confirmed by both intraoperative inspection and postoperative follow\u2010up ultrasound examinations.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>The median age of the cohort was 24.0 (interquartile range (IQR), 20.5\u201328.7) years, and parity ranged from 0 to 3. All affected ovaries were significantly enlarged compared with non\u2010affected ones (median cross\u2010sectional area, 18.1 (IQR, 12.4\u201326.4) cm<jats:sup>2<\/jats:sup> vs. 4.3 (IQR, 2.9\u20136.2) cm<jats:sup>2<\/jats:sup>, <jats:italic>P<\/jats:italic> &lt; 0.01). We could distinguish two distinct sonographic patterns of torted ovaries: there were numerous small peripheral follicles in the ovarian parenchyma in nine cases, and there was a solid\u2010appearing mass with hypo\u2010 and hyperechogenic foci in five cases. Comparison of the ultrasound images of patients with short\u2010term vs. long\u2010term abdominal pain revealed that the solid\u2010appearing ovary was more common in the latter group (0\/6 vs. 5\/8, <jats:italic>P<\/jats:italic> = 0.03), while there was no significant difference between groups in the presence of free pelvic fluid or median ovarian cross\u2010sectional area. Intraovarian blood flow was diminished or absent in five of the eight patients in whom color Doppler imaging was performed.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>Ultrasound images of twisted normal adnexa may vary according to the duration of the condition, reflecting the pathological series of events of increased ovarian congestion and necrosis. Recognition of the different sonographic features of twisted normal adnexa may assist in the correct diagnosis of these patients. Copyright \u00a9 2008 ISUOG.
