Ovarian torsion is a gynecological emergency where the ovary, and sometimes the fallopian tube, twists around its vascular pedicle, compromising blood flow. This acute rotation can lead to ischemia, necrosis, and severe pelvic pain, often accompanied by nausea and vomiting. Prompt diagnosis is crucial to preserve ovarian viability and prevent irreversible damage.
Ultrasound plays a vital role in identifying ovarian torsion, typically revealing an enlarged, edematous ovary with absent or compromised Doppler flow. The “whirlpool sign,” indicating twisted vessels, is a highly specific but not always present finding. Early recognition and surgical intervention are essential for successful outcomes in this time-sensitive condition.
