Diagnosis: Hematometrocolpos. This is not a common ED diagnosis but develops in the setting of a vaginal obstruction - in this case the imperforate hymen. Your suspicion for this diagnosis should increase in child with features of puberty, primary amenorrhea, and intermittent abdominal pain. The classic physical exam finding is a bluish bulging membrane at the introitus. US is used to distinguish between hematocolpos (fluid in vagina) vs hematometrocolpos (fluid in BOTH the vagina and the uterous). Treatment is generally an incision of the bulging tissues.

See below for YouTube video links to both the long and sort axis views of the uterous and bladder.

Thank you for your great images!
