Isolated fallopian tube torsion: two case reports of a rare entity.

Isolated fallopian tube torsion is a rare entity that is difficult to diagnose, as its clinical presentation is often highly nonspecific. Early diagnosis is important to avoid damage or loss of the fallopian tube or even the ovary, as this diagnosis occurs predominantly in women of child-bearing age. Imaging may be helpful in suggesting this difficult diagnosis, with confirmation of this entity made in the operating room. Treatment can range from detorsing the tube to salpingectomy or even salpingo-oopherectomy. Here, we present two cases of isolated fallopian tube torsion, followed by a discussion of its imaging findings.
