Role of ultrasound in diagnosing isolated torsion of fallopian tube

Abstract

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.

Isolated Fallopian Tube Torsion: A Unique Ultrasound Identity or a Serial Copycat?

“…In 2011, Mashiach et al 14 reported a 74.6% US detection rate for ovarian torsion compared to the 23% to 66% rates reported in earlier studies. By contrast, the US detection rate for isolated fallopian tube torsion has remained consistently low, 3,5,8,12,13,15 possibly because of the rarity of the disorder. Accordingly, in this cohort, isolated fallopian tube torsion was accurately diagnosed by US in only 8 of 27 patients (29.6%).…”

Quadruple torsion of the fallopian tube in an 18-year-old virgin: a rare twist

“…Sun et al analysed the ultrasonic features of isolated fallopian tube torsion in 11 patients, only 4 cases were diagnosed correctly before surgery (36.4%). The most common findings where cystic masses (36.4%) and tubular structures (27.3%) 5. Also, in a recently published retrospective cohort study, Raban et al evaluated the diagnostic value of ultrasound imaging in 27 patients with a surgical diagnosis of isolated fallopian tube torsion.…”

The “Double Ovary” Sign

“…13 Previous reports have characterized findings such as hydrosalpinx or paraovarian cysts on sonography as signs which point toward IFTT, though these findings are seen in a range of diseases. 2,4,14 In the following case series, we describe a new and unique imaging sign, allowing for the preoperative diagnosis of isolated fallopian tube torsion, the "double ovary" sign. This sign is defined by the presence of two adjacent ovary-like structures in the adnexa, one which is the normal ovary and the other which is the ipsilateral twisted fallopian tube.…”
