Isolated tubal torsion: Specific signs on preoperative computed tomography and magnetic resonance imaging

Isolated torsion of the fallopian tube is a rare cause of lower abdominal pain and commonly occurs after menarche. Prompt identification of this entity can prevent irreversible vascular damage, but the diagnosis is rarely made before surgery due to nonspecific clinical and imaging features. We report a case of isolated tubal torsion with specific imaging features on preoperative computed tomography and magnetic resonance imaging.
