Tubo-ovarian abscess

Case contributed by Dr Mostafa Mahmoud El Feky


Persistent pelvic pain for a few days, fever, vaginal discharge and leucocytosis.

Patient Data

Age: 55
Gender: Female

MRI pelvis with contrast

Bilateral pyosalpinx, larger on the right side, measuring 3 cm and 1.3 cm in tubal calibre for the right and left sides respectively.  Both demonstrate wall enhancement and diffusion restriction. This is associated with surrounding stranding of the pelvic fat and minimal pelvic fluid.

Case Discussion

This case demonstrates tubo-ovarian abscesses with pyosalpinges, and pelvic peritonitis. The ovaries couldn't be distinguished separately from the fallopian tubes.

Tubo-ovarian abscess is a late complication of pelvic inflammatory disease (PID). It is important to differentiate it from other causes of pelvic abscess like appendiceal abscess and diverticular abscess.

It can be difficult on ultrasound to differentiate the nature of the inflammatory mass and also if associated with gas formation is hard to differentiate from bowel gas.

MRI is the best choice if clinically suspecting a pelvic inflammatory mass.
