Conclusion
All patient of asymmetrical enhancement of ovarian veins were accompanied with fallopian tube thickening.
Since fallopian tube thickening are specific findings to ovarian torsion,
asymmetrical enhancement of ovarian veins may have little diagnostic value of torsion.
But all of the asymmetrical presence of contrast medium cases were hemorrhagic infarction.
Differentiation of hemorrhagic from nonhemorrhagic infarction is important for treatment planning.
This finding may suggest hemorrhagic infarction on CECT alone was performed,
even if abdomen is only scanned.
Our study had a number of limitations.
Our observations were subject to selection bias because only patients referred for CT or MRI were included.
Retrograde flow of ovarian veins was reported in about 40% asymptomatic women.
Since serial CT is not available,
it is unknown whether flow of ovarian veins are anterograde or retrograde before disease.
Asymmetrical presence of contrast medium of ovarian veins in cases of lower abdominal pain should raise suspicion of ovarian torsion and hemorrhagic infarction.
