Pubic osteomyelitis resulting in rectovaginal fistula in an adolescent female.

Background: Pelvic osteomyelitis is a rare but serious condition that has the potential for systemic and muscular complications if left untreated. The diagnosis is difficult due to the relative rarity of the disease, the difficulty of localizing the site of the infection, and the tendency for the presentation to mimic other disease processes.

Case: A 13-year-old female who presented with complaint of severe right lower abdominal pain thought to be related to a hemorrhagic cyst but was found to have pubic osteomyelitis resulting in an abscess and vaginal fistula.

Conclusion: Although rare, pelvic osteomyelitis should be included in the differential diagnosis of pelvic pain.
