Pelvic inflammatory disease, pyosalpinx and tubo-ovarian abscess are all part of a spectrum of gynaecological infection, related to sexually transmitted disease.
Usually the diagnosis is clinical, along with trans-vaginal ultrasound. On occasion the patient may reach as far as MRI.
The fallopian tube is typically
- contained high T2 signal fluid, although this may vary
- thick enhancement of the wall of the fallopian tube
- avid internal diffusion restriction ( it is essentially a tube abscess so restricts like abscesses observed elsewhere ).
Treatment is surgical.
