Clinical Practice and Cases in Emergency Medicine

Hematometrocolpos is a rare congenital abnormality of the female urogenital system that leadsto an imperforate hymen and subsequent retrograde menstruation. We present the case of a14-year-old female patient who presented to the emergency department with amenorrhea andabdominal pain, and was found to have an imperforate hymen and hematometrocolpos on transabdominalpoint-of-care ultrasound. It is important for emergency physicians to consider thisdiagnosis in pubescent female patients presenting with abdominal pain, as missed diagnosis canlead to infertility and other complications.
