Isolated Fallopian-Tube Torsion: A Case Series

Abstract

Abstract Background: Isolated Fallopian-tube torsion is a rare event, with a reported incidence of 1:1500000. This is a single center report of 4 cases of isolated Fallopian tube torsion presenting at our single center from 2010 to 2012. Cases: All 4 cases were women presenting with right- sided lower abdominal pain. Three of the women were in their early 20s, whereas 1 woman was in her early 50s. Results: Ultrasound scan findings were nonspecific and variable, for example, ovarian cyst with echogenic focus, or normal adnexa with free fluid in the pouch of Douglas. One of the cases was a suspected heterotopic pregnancy. Laparoscopy in all these cases revealed isolated Fallopian-tube torsion. In 3 cases, salpingectomy was performed. In 1 case, tube-conserving surgery was performed to untangle the tube. All of the women recovered well after surgery. Conclusions: The incidence appears to be higher than as reported. The cause of Fallopian-tube torsion is unknown. It can be associated with an ovarian or paraov...
