Bilateral enterobius vermicularis salpingo-oophoritis.

Inflammatory pelvic disease secondary to infection with Enterobius vermicularis is rare in that pinworms are usually asymptomatic inhabitants of the terminal small bowel and cecum. When these parasites do cause symptoms, however, there is a spectrum of gastrointestinal and genitourinary complaints. A case is presented of a woman with bilateral abdominal pain that was found to be due to a combination of parasitic and bacterial (Bacteroides fragilis) infection. The parasitic fallopian tube infection may have predisposed the fallopian tubes to a microbial tuboovarian abscess.
