Successful outcome after spontaneous first trimester intra-amniotic haematoma and early preterm premature rupture of membranes.

A spontaneous intra-amniotic haematoma is a rare cause of preterm premature rupture of the membranes (PPROM) but can have significant fetal and maternal consequences. It has previously been reported to occur in the second and third trimesters but not in an earlier gestation. We present a case that presented acutely in the first trimester of pregnancy, which leads to early PPROM at 15 weeks and spontaneous preterm delivery at 28 weeks of gestation. There were no maternal complications during the pregnancy.
