A pyosalpinx refers to a situation where the Fallopian tubebecomes filled (and often distended) with pus.
Pathology
A pyosalpinx often tends to be a complication of background pelvic inflammatory disease (PID) where inflammation. Inflammation results in tubal and peritubal adhesions with superimposed obstruction of the fimbrial end. It canPyosalpinx can be a component of a tubo-ovarian abscess. Being unable to drain, the fallopian tube distends with pus, resulting in a pyosalpinx.
Radiographic features
A pyosalpinx may be seen as a thickened fallopian tube and may or may not be associated with debris containing tubal distention. The Fallopian tube may be distended.
Pelvic ultrasound
It may be seen seen as a
- dilated
serpantineserpentine / tubular stucture in the pelvis. Low -
low-level echoes
are more commonly encountered in a pyosalpinxdue to the higher protein content of the debris within the tube distinguish a pyosalpinx from a hydrosalpinx 4,6.
Pelvic MRI
Morphological appearances of a pyosalpinx can sometimes be be indistinct from a simple simple uncomplicated tubal dilatation (hydrosalpinx) 1. As opposed to a simple hydrosalpinx, in pyosalpinx the tube wall may appear thickened 3 and havehyper-enhancing hyperenhancing tubal walls with surrounding inflammation.
