Hydrometrocolpos is a pelvic cystic mass representing the distension of the vagina and uterus due to obstructive congenital anomalies of the female causing accumulation of fluid secretions in the vagina and endometrial cavity. Prenatal diagnosis is uncommon and usually noticed during the adolescent period for failure to see menses with cyclic abdominal pain, abdominal mass, and local compressive symptoms. Late diagnosis after delivery of newborns with this condition results in poor outcomes from local compressive symptoms.
Here, we present a case diagnosed with congenital hydrometrocolpos at 39 weeks of gestation during routine third-trimester ultrasound scanning. The newborn was delivered vaginally and huge hydrometrocolpos secondary to imperforate hymen was diagnosed postnatally, and a hymenectomy was done and the newborn was discharged and improved from the hospital.
Although congenital hydrometrocolpos occurs rarely, it is also better to suspect prenatally in a female fetus with a cystic pelvic mass. Antenatal ultrasound diagnosis of this condition will help to make decisions early and to prevent further complications which might occur both intrauterine and after birth.
阴道子宫积水是一种盆腔囊性肿物，表现为因女性先天性梗阻性畸形导致阴道和子宫扩张，致使阴道和子宫内膜腔内液体分泌物积聚。产前诊断并不常见，通常在青春期因月经未至伴周期性腹痛、腹部肿块及局部压迫症状而被发现。患有这种疾病的新生儿出生后诊断延迟会因局部压迫症状导致预后不良。
在此，我们报告一例在孕晚期常规超声扫描时于妊娠39周被诊断为先天性阴道子宫积水的病例。新生儿经阴道分娩，产后诊断为处女膜闭锁继发巨大阴道子宫积水，并进行了处女膜切开术，新生儿出院时病情好转。
虽然先天性阴道子宫积水很少见，但对于有盆腔囊性肿物的女性胎儿，产前也最好加以怀疑。对这种疾病进行产前超声诊断有助于尽早做出决策，并预防可能在宫内和出生后发生的进一步并发症。
