Pathology
A pyosalpinx often tends to be a complication of background pelvic inflammatory disease (PID). Inflammation results in tubal and peritubal adhesions with superimposed obstruction of the fimbrial end. Pyosalpinx 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. The fallopian tube may be distended.
Ultrasound
dilated serpentine/tubular structure in the pelvis
low-level echoes due to the higher protein content of the debris within the tube distinguish a pyosalpinx from a hydrosalpinx 4,6
MRI
Morphological appearances of a pyosalpinx can sometimes be indistinct from simple uncomplicated tubal dilatation (hydrosalpinx) 1. As opposed to a simple hydrosalpinx, in pyosalpinx the tube wall may appear thickened 3 and have hyperenhancing tubal walls with surrounding inflammation.
Signal characteristics within the tubular lumen have been described as 5
T1: variable due to varying protein content
T2: often hyperintense, with characteristic amorphous shading
T1 C+ (Gd): thick rim enhancement
DWI/ADC: restricted diffusion in the fallopian tube
