Bilateral Pyosalpinx Due to a 16-Year-Old Intrauterine Device Presented as Appendicitis.

ABSTRACT

Pyosalpinx is the collection of pus in the fallopian tube. Pyosalpinx usually follows pelvic inflammatory disease, sexually transmitted disease, or rarely non-sexually transmitted infection. This is the first-ever report of bilateral pyosalpinx due to intrauterine device in situ for the past 16 years, which presented as appendicitis. Pyosalpinx should be considered in female patients with lower abdominal pain.
