Congenital vaginal obstruction with intrauterine hydrometrocolpos: A case report

Intrauterine hydrometrocolpos is a rare condition caused by congenital vaginal obstruction. Imperforate hymen is the most common cause and manifests as a huge abdominopelvic mass. Ultrasonography is an invaluable tool in screening and evaluation of fetal intra-abdominal mass but even with serial ultrasonography it may be very difficult to delineate the exact site of origin and come to a diagnosis. MRI is the most reliable and sensitive modality to evaluate complex malformations/ masses. In a female child born with cystic abdominopelvic mass a thorough neonatal examination after birth focusing on the urogenital system and the extremities will give a significant clue in diagnosis and subsequent management of hydrometrocolpos. Here we present a case of intrauterine hydrometrocolpos which remained in diagnostic dilemma until the postnatal period. Key words: complex malformations, congenital vaginal obstruction, hydrometrocolpos
