|Patient: 1 day old female|
|History: Fullterm female neonate transferred from outside hospital with "a soft tissue mass bulging from the introitus." Antenatal sonogram, obtained 2 days prior to delivery, demonstrated a midline pelvic mass near the bladder. Abnormalities on physical exam: Abdomen with a ballotable mass. External Genitalia with normal female features and imperforate hymen.|
|Findings: Postnatal Pelvic Ultrasound: FINDINGS: Midline complicated fluid collection posterior to the bladder.|
|Diagnosis: Hydrocolpos secondary to imperforate hymen|
|Discussion: Hydrocolpos is the distension of the vagina caused by accumulation of fluid due to congenital vaginal obstruction. The obstruction is often caused by an imperforate hymen or, less commonly, a transverse vaginal septum or vaginal atresia. The term "hydrometrocolpos" should be used when the expanded fluid-filled vaginal cavity is associated with distention of the uterine cavity itself. Hymenotomy was performed and 100 mL of serosanguinous fluid was drained. Follow-up ultrasound verified drainage of the obstructed vaginal opening. Patient discharged home. Hydrocolpos can be associated with genetic syndromes as well: 1) McKusick-Kaufman syndrome (MKS): genital abnormalities [Females:most commonly hydrocolpos / Males: hypospadias/chordee/cryptorchidism], Polydactyly, heart defects 2) Bardet-Biedl syndrome: presentation similar to MKS in neonatal period; with renal abnormalities/dysfunction, vision loss, developmental delay, obesity later on in life|
