AFallopian tube torsion is a type of adnexal torsionand and usually occurs in association with an ovarian torsion(when it is then termed a tubo-ovarian torsion). An isolated fallopian fallopian tube torsion is rare but can occur.
Pathology
An isolated tubal torsion can occur as a late complication of tubal ligation 1-2,2.
Other risk factors for an isolated fallopian tube torsion include3,8
- intrinsic factors
- pelvic inflammatory disease (PID)
- anatomical abnormalities
- hydrosalpinx
- haematosalpinx: can also be a consequence
- long mesosalpinx
- physiological abnormalities
- tubal neoplasm
- extrinsic factors
- adhesions
- adnexal venous congestion
- adjacent ovarian or paraovarian masses (e.g. paraovarian cysts)
- uterine masses
- gravid uterus
Location
There is a well recognised-recognised right sided-sided predilection 9
Radiographic features
Ultrasound
Reported sonographic findings include 3,5
- a normal-appearing uterus and ovaries with normal flow
-
freefree fluid - a dilated tube with thickened, echogenic walls and internal debris
- a convoluted echogenic mass thought to represent a thickened, torsed tube
-
sonographic whirlpool sign: described as a relatively specific sign
ofof tubal torsion 7
CT
Reported primary CT CT findings of isolated tubal torsion include3-4,4
- an adnexal mass
- twisted appearance to the fallopian tube with dilated tube greater than 15 mm
- thickened and enhancing tubal wall and luminal CT attenuation greater than 50 HU
units, compatible with haemorrhage
Secondary signs include
- free intrapelvic fluid
- peritubular fat stranding
- enhancement and thickening of the broad ligament
, - regional ileus
