Clinical Characteristics of Women with Isolated Fallopian Tube Torsion Compared with Adnexal Torsion



Isolated fallopian tube torsion (IFTT) is a rare gynecological entity and its diagnosis is challenging.


To compare clinical characteristics, sonographic findings, surgical management, and outcomes of women with surgically verified IFTT compared to those diagnosed with adnexal torsion.


A retrospective case-control study in a university hospital was conducted. Thirty-four women with surgically verified IFTT between March 1991 and June 2017 were compared to 333 women diagnosed with adnexal torsion within the same time period.


Both groups presented primarily with abdominal pain, which lasted longer prior to admission among the IFTT group (46.8 ± 39.0 vs. 30.0 ± 39.4 hours, P < 0.001). Higher rates of abdominal tenderness with or without peritoneal signs were found in the adnexal torsion group (90.3% vs. 70.6%, P < 0.001). Sonographic findings were similar; however, an increased rate of hydrosalpinx was found among the IFTT group (5.9% vs. 0.0%, P = 0.008). Suspected adnexal torsion was the main surgical indication in only 61.8% of IFTT cases compared with 79.0% in the adnexal torsion group (P = 0.02). Salpingectomy with or without cystectomy was more commonly performed in the IFTT group (35.3% vs. 1.5%, P < 0.001). The leading pathological findings among the IFTT group were hydrosalpinx and paraovarian cysts.


The clinical signs and symptoms of IFTT and adnexal torsion are similar. Although sonographic imaging demonstrating a paraovarian cyst or hydrosalpinx may be helpful in diagnosing IFTT, it is rarely done preoperatively.
