Prenatal diagnosis of isolated fetal hydrometrocolpos: A case report

Abstract

A rare congenital condition known as hydrometrocolpos (HMC) is characterized by the buildup of secretions in the vagina and uterus as a result of distal obstruction; this condition is frequently linked to imperforate hymen. This case report presents a prenatal diagnosis of isolated HMC in a 30-year-old primigravida, detected at 36 weeks gestation. Initial ultrasound revealed a large cystic mass, confirmed by fetal magnetic resonance imaging to be HMC. Postnatal examination of the new born confirmed imperforate hymen and HMC, which was effectively treated with hymenotomy, resulting in early resolution. This case underscores the importance of prenatal imaging in the early identification and management of HMC to prevent potential complications.
