Delayed diagnosis of imperforate hymen with huge hematocolpometra: A case report

Abstract

BACKGROUND Imperforate hymen is a rare obstructive anomaly of the female reproductive tract. It is associated with complications, such as cyclical abdominal pain, urinary retention, and pelvic mass. CASE SUMMARY A 13-year-old girl presented several times to the emergency room with lower abdominal pain for a year. She received conservative treatment, such as pain control, at each visit. She visited our gynecological clinic for worsening pain, and a 14-cm hematocolpos was found on ultrasonography. She was finally diagnosed with an imperforate hymen with hematocolpometra. Hymenectomy was performed, which resulted in event-free regular cyclical menstruation. CONCLUSION Imperforate hymen should be considered in a premenarcheal adolescent girl with periodic abdominal pain.
