Clinical Communications: AdultsAcute Urinary Retention Caused by an Ovarian Teratoma-A Unique Pediatric Presentation and Review

BackgroundAcute urinary retention (AUR) is a rare diagnosis both in pediatric and adult female populations, especially when compared to adult males. AUR occurs in women at a rate of 7 in 100,000 per year in a 1:13 female to male ratio. Multiple studies have shown that within the pediatric population AUR is far less common in females and is caused by different pathologies than AUR in adult women.Case ReportWe report the case of an 11 year-old prepubescent female who presented to the emergency department with acute urinary retention found to be caused by a mature cystic ovarian teratoma.Why should an emergency physician be aware of this?Our case is unique in that it describes an ovarian mass leading to AUR which has not previously been described in the pediatric literature. We will review the causes of AUR in the pediatric female population and compare these to the causes of AUR in other populations.
