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.
