Prenatal Ultrasonographic Diagnosis of Hydrometrocolpos

Fetal hydrometrocolpos and congenital imperforate hymen: Prenatal and postnatal imaging features

“…4 Vaginal obstruction and accumulation of fluid in the genital tract leads to distension of the vagina and uterus. [4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20][21][22][23] There is a pear-shaped cystic mass with fluid-debris level between the bladder and the rectum. 5 In the reported cases of hydrometrocolpos secondary to isolated congenital imperforate hymen, the prenatal US findings have been well described.…”

Challenges in prenatal diagnosis of foetal anorectal malformation and hydrocolpos – Case report

“…There is no data on fetal presentation of hydrometrocolpos due to the rarity of the disease and the difficulty in prenatal diagnosis. The prevalence of congenital dilatation of the uterus and vagina causing hydrometrocolpos is less than 1 per 30,000 births with the first report published in 1856 [ 5 , 6 ].…”

“…The content of fluid accumulating may be clear (urine) or turbid with a fluid-debris level on sonography (meconium or cervical secretions. The spectrum of hydrocolpos is quite broad, ranging from mild cases that may remain undetected until adolescence to more severe conditions described prenatally as a large pelviabdominal cystic mass, just like in the case [ 6 ].…”

Fetal ultrasound diagnosis allows effective early postnatal treatment of hematometrocolpos

“…Most reports of fetal hematometrocolpos describe a pear-shaped cystic mass with fluid-debris level in the fetal pelvis posterior to the bladder and anterior to the rectum and most are diagnosed after 32 weeks of gestation, 3,4 however Winderl et al reported a case at 25 weeks of gestation which appears to be the earliest fetal diagnosis in the literature. 5 Due to the low incidence of fetal hematometrocolpos, the associated ultrasound findings often prompt clinicians to request further imaging, mostly fetal MR scans to clarify the diagnosis and the extent of the lesion.…”
