Abstract:
Objectives: 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.
Case presentation: 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.
Conclusions: 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.
