An ovary with a twist: a case of interesting sonographic findings of ovarian torsion.

An otherwise healthy young woman presented to the Emergency Department with abdominal pain. Multiple diagnoses were considered, as must be in cases of women with lower quadrant abdominal pain. Rapid identification of an abnormally enlarged ovary in close proximity to the opposite ovary on pelvic ultrasonography suggested the diagnosis of ovarian torsion. This was verified on laparoscopy. Of note is the fact that normal Doppler flow to both ovaries was demonstrated on pelvic ultrasound. We present this case, and its associated images, with the intent to highlight a readily identifiable sign of ovarian torsion for emergency physicians and to briefly review ovarian torsion's salient clinico-pathologic features.
