BACKGROUND: Isolated fallopian tube torsion during pregnancy is a rare condition, and only 16 cases have been reported. In all but 1 case the right tube was affected. We report the second case of isolated left fallopian tube torsion during pregnancy. CASE: A 23-year-old primigravida presented at 22 weeks of gestation with left lower abdominal pain. Sonography depicted a simple cystic mass adjacent to the left uterine border. Laparotomy revealed torsion of the left hydrosalpinx together with a paraovarian cyst. The patient delivered a healthy infant at term after an otherwise-uneventful pregnancy. CONCLUSION: As the gravid uterus increases the risk for fallopian tube torsion, this condition should be included in the differential diagnosis of lower abdominal pain during pregnancy.
