[Fallopian tube torsion: five cases with no other element].

Isolated Fallopian tube torsion is extremely rare and diagnosis is difficult. Laparoscopy is necessary, but surgery is often performed too late to preserve the tube. Five cases of Fallopian tube torsion with no other element are presented. Diagnostic difficulties, causes, ultrasonographic findings and treatment are discussed. Early diagnosis and surgical intervention is mandatory when exceptional isolated Fallopian tube torsion is suspected particularly in a nulliparous young woman.
