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

Congenital imperforate hymen is probably the most common obstructive anomaly of the female reproductive tract. The accumulation of fluid in the genital tract leads to a distended uterus and vagina, causing hydrometrocolpos. Prenatal diagnosis of fetal hydrometrocolpos is uncommon, with only 22 cases reported in the literature and only a few cases of prenatal imaging of this condition available to date. The main ultrasound finding is a fetal pelvic mass posterior to the bladder and anterior to the rectum. We present the case of a 37-week female fetus with a fetal pelvic mass detected in a routine obstetric ultrasound examination, and the correlation between the prenatal and postnatal findings.

Ultrasonographic diagnosis of congenital hydrometrocolpos in prenatal and newborn period: a case report

Our purpose is to present the ultrasonographic findings of a rare case of prenatally and postnatally congenital hydrometrocolpos secondary to imperforate hymen. By ultrasonography (US) at 38 weeks of gestation, a retrovesical, 60 x 43 mm pelvic cystic mass, was demonstrated in a female fetus. After delivery, US of the newborn revealed a 77 x 60 mm retrovesical, pear-shaped cystic structure with internal echoes, interpreted as congenital hydrometrocolpos. Mild pelvicaliectasis in the left kidney was associated. At physical examination imperforate hymen was detected and a hymenotomy was done. After the hymenotomy, complete regression of the hydrometrocolpos and of the left renal pelvicaliectasis was demonstrated sonographically.

Prenatal sonographic diagnosis of fetal persistent urogenital sinus with congenital hydrocolpos

We report a case of persistent urogenital sinus with hydrocolpos and associated renal anomalies diagnosed prenatally at 30 weeks' gestation. The prenatal findings were confirmed on postnatal ultrasonography and genitogram with voiding urethrogram. The imaging features and a review of the literature are discussed. The possibility of hydrometrocolpos secondary to urogenital sinus should be considered on prenatal sonography in the presence of a presacral cystic mass with clear urine or turbid contents and a fluid-debris level (cervical or vaginal secretions). Because the prognosis and neonatal management of isolated hydrocolpos (which usually resolves spontaneously) differ greatly from those of hydrocolpos associated with a cloacal malformation, it is important to diagnose prenatally any associated anomalies in order to allow optimal postnatal management.

The role of dynamic magnetic resonance urography in complex neonatal hydrometrocolpos

Urinary hydrometrocolpos is rarely diagnosed and is most often attributed to a persistent urogenital sinus or a cloaca. We report the case of a neonate in which the use of dynamic MRI allowed accurate preoperative diagnosis of urinary hydrometrocolpos secondary to ectopic drainage of a small left pelvic kidney, associated with a bicornuate uterus.

Mucocolpos associated with bladder exstrophy: a case report

INTRODUCTION

We present the first reported case demonstrating an association of mucocolpos and bladder exstrophy.

MATERIALS

A term baby girl presented with bladder exstrophy and underwent a successful primary bladder closure and ureteral reimplantation. Subsequently, she presented with a fluid-filled pelvic mass which was found to be a mucocolpos.

RESULTS

Surgical drainage of the collection was required.

CONCLUSION

Mucocolpos should be considered in the differential diagnosis of a pelvic mass in a patient with bladder exstrophy.
