Teenagers account for 15% to 20% of the cases of pelvic inflammatory disease (PID).1 Abdominal pain, abnormal vaginal discharge or bleeding, and fever are the hallmark symptoms seen in these patients. However, a wide range of other nonspecific findings may confound the diagnosis. It has traditionally been thought that sexual activity is a prerequisite for acquiring PID. We report the first case, to our knowledge, of a pelvic abscess secondary to vaginal voiding that resulted in a nonsexually acquired ascending infection.
