Abdominal swelling and obstructive uropathy due to hematometrocolpos secondary to imperforate hymen: a case report

Abstract

Imperforate hymen is an uncommon congenital anomaly of the female genital tract and can lead to the collection of blood in the vagina and the uterus. Most patients are not diagnosed until menarche when they present with symptoms such as cyclic abdominal and pelvic pain, constipation, tenesmus, back pain, and difficulties with urination in association with lack of menses. We discuss the case of an adolescent female who presented with the complaint of an increasing abdominal swelling along with the urgency and a sense of incomplete urination. She had not attained menarche. A diagnosis of hematometrocolpos was made based on computed tomography findings. Subsequent perineal examination revealed a bulging imperforate hymen. Hymenotomy was performed with complete resolution of the symptoms. This case highlights the importance of keeping a high index of suspicion for this condition in patients presenting with these symptoms and the importance of appropriate gynecologic examination.
