Imperforate hymen
Imperforate Hymen
Imperforate hymen (pronounced: im-PER-for-ate HY-men) is a congenital disorder where a hymen without an opening completely obstructs the vagina. It is caused by a failure of the hymen to perforate during fetal development.
Etymology
The term "imperforate" is derived from the Latin words "in" meaning "not" and "perforatus" meaning "pierced". The term "hymen" is derived from the Greek god of marriage, Hymenaios.
Symptoms
Symptoms of an imperforate hymen include amenorrhea (absence of menstruation), abdominal pain, and cyclic pelvic pain. In neonates, it may present as a bulging, bluish membrane due to the accumulation of vaginal and uterine secretions (hydrocolpos or hydrometrocolpos).
Diagnosis
Diagnosis is typically made by physical examination, although imaging studies such as ultrasound or MRI may be used to confirm the diagnosis and rule out other anomalies.
Treatment
Treatment typically involves hymenectomy (surgical removal of the hymen), which creates an opening in the hymen to allow for the normal flow of menstrual blood and other secretions.
