Spontaneous Rupture of an Unscarred Gravid Uterus in a Primigravid Woman at 32 Weeks of Gestation

الملخص EN

Uterine rupture usually occurs in a scarred uterus, especially secondary to prior cesarean section.

Antepartum uterine rupture in an unscarred uterus is extremely rare.

We report a case of spontaneous rupture of an unscarred gravid uterus at 32 weeks of gestation in a primigravid woman.

Ultrasonography and magnetic resonance imaging showed a bulging cystic lesion communicating with the intrauterine cavity.

Operative findings during emergent cesarean section revealed uterine perforation in the right cornual area and a prolapsed, nonbleeding amniotic sac.

The left cornual area was also focally thin.

An arcuate uterus was suspected based on follow-up hysterosalpingography.

Antepartum uterine rupture tends to occur in the uterine cornual area.

In this case, Müllerian duct anomalies may have been associated with focal myometrial defects.
