Abstract Aim To summarize the ultrasonic features of isolated fallopian tube torsion ( IFTT ) by retrospectively analyzing cases presenting at our hospital. Methods This analysis was approved by the ethical committee of our hospital. Medical records of surgically proven IFTT patients admitted to our hospital since 2002 were collected. Clinical features and preoperative diagnoses of the patients were analyzed retrospectively. Ultrasonic images were reviewed and characteristics, including location, size, shape, echo and vascularity of the fallopian tube, were summarized. Results Eleven patients with IFTT were studied. No obvious association was found between the torsion and menstruation cycle. Only four accurate diagnoses were made before the operation. Degrees of torsion ranged 360–2160°. Most of them (9/11, 81.8%) were greater than 720°. Sonograms of the 11 patients could be classified into four types: cystic masses, tube‐like structures, heterogeneous masses and whirlpool signs. Cystic masses were the most commonly seen type (4/11, 36.4%), followed by tubular structures (3/11, 27.3%). Whirlpool sign was believed to be the most specific sign in diagnosing IFTT . Conclusion Through review of the authors' experiences, it is possible to diagnose IFTT preoperatively by ultrasound. Sonograms of the IFTT could be divided into four types while clinical significance of this classification requires further confirmation.
