A fallopian tube torsion is a type of adnexal torsion and usually occurs in association with an ovarian torsion (when it is then termed a tubo-ovarian torsion). An isolated fallopian tube torsion is rare but can occur.
Pathology
An isolated tubal torsion can occur as a late complication of tubal ligation 1,2.
Other risk factors for an isolated fallopian tube torsion include 3,8
-
intrinsic factors
-
anatomical abnormalities
hematosalpinx: can also be a consequence
long mesosalpinx
-
physiological abnormalities
-
extrinsic factors
adhesions
adnexal venous congestion
adjacent ovarian or paraovarian masses (e.g. paraovarian cysts)
uterine masses
gravid uterus
Location
There is a well-recognized right-sided predilection 9
Radiographic features
Ultrasound
Reported sonographic findings include 3,5
a normal-appearing uterus and ovaries with normal flow
free 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 of tubal torsion 7
CT
Reported primary CT findings of isolated tubal torsion include 3,4
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, compatible with hemorrhage
Secondary signs include
free intrapelvic fluid
peritubular fat stranding
enhancement and thickening of the broad ligament
regional ileus
