Edematous, T2 hyperintense left fallopian tube is identified, best appreciated on the sagittal T2 images. 1. Failure to consider ovarian torsion in the differential diagnosis is not uncommon, given the relative infrequency of this condition. Magnetic resonance imaging demonstrated ovarian enlargement and edema. Early recognition and restoration of blood flow are important to avoid irreversible ovarian damage. Although this sign is specific for ovarian torsion, yet it had been variably reported as seen in 13–88% of patients with ovarian torsion , , . The incidence of ectopic pregnancy has increased from 0.37% of pregnancies in 1948 to approximately 2% of pregnancies in 1992 (,1).
