title: Prevalence of abnormal CT findings in patients with proven ovarian torsion and a proposed triage schema.
abstract: Many women with ovarian torsion present with nonspecific abdominal/pelvic pain and initially receive computed tomography (CT). We hypothesize that the CT scans preformed on these women will all show abnormalities of the involved ovary. Our purpose is to review cases of surgically proven ovarian torsion at our institution over the last 20 years, assessing CT findings in women with ovarian torsion. A retrospective review of all patients at our institution with surgically proven ovarian torsion from 1985-2005 was conducted. Two physicians reviewed available CT reports, and a radiologist reviewed all available images. CT was obtained in 33% of the 167 patients. Dictated reports were available for 28 studies; all described an enlarged ovary, ovarian cyst, or adnexal mass of the involved ovary. Radiologist review of the available CT images confirmed these findings. This series supports the claim that a CT scan with well-visualized normal appearing ovaries rules out ovarian torsion, while abnormal pelvic findings or failure to visualize the ovaries in women with pelvic pain necessitates further evaluation of torsion.
