Rupture of uterus in a primigravida prior to onset of labor.

Spontaneous rupture of the uterus in a primigravida is very rare. Furthermore, uterine rupture in a primigravida prior to the onset of active labor is extremely uncommon, with very few reported cases. We present a case of antepartum uterine rupture in a 20-year-old primigravida in whom the clinical features resembled those of abruptio placentae.
