In this radiology lecture, we discuss the ultrasound appearance of ovarian torsion.
Rotation of ovarian vascular pedicle with obstruction to venous outflow and arterial inflow.Enlarged, heterogenous ovary due to hemorrhage and edema.Small peripheral cysts with “follicular ring” sign: Thick, hyperechoic rim surrounding follicles of torsed ovary.Classically, absent vascular flow.However, up to 60% of patients with torsion have normal color Doppler findings, and arterial flow may even be preserved!Most common finding is decreased or absent venous flow.Twisted vascular pedicle: Most definitive sign of torsion, present in up to 88% of patients.“Whirlpool” sign: Flow within the twisted vascular pedicle.Click the YouTube Community tab or follow on social media for bonus teaching material posted throughout the week!
