A broad ligament pregnancy is an extremely rare condition. The eventuality of such pregnancies reaching full term is even rarer. A full-term broad ligament pregnancy occurring through a rent in a previous lower segment caesarean scar has only been mentioned in literature but not reported. Our patient is an unbooked case, reported to us at 39 weeks of pregnancy. On clinical examination, an ultrasound and an MRI, a diagnosis of abdominal pregnancy was made. Ultimately the final diagnosis was made only on laparotomy. A broad ligament pregnancy was found with a rent in the previous caesarean scar communicating the fetal sac.
