Primary abdominal pregnancy in the uterosacral ligament with haemoperitoneum: a near miss.

Primary abdominal pregnancy has a higher mortality rate than other ectopic gestations. Delayed diagnosis can be associated with catastrophic haemorrhage. This report describes a spontaneous conception which occurred in the uterosacral ligament in a woman with no known risk factors for an ectopic pregnancy. Extrauterine pregnancy was diagnosed by ultrasound and laparoscopy was performed secondary to haemoperitoneum, which revealed a pregnancy implanted in the right uterosacral ligament. The rarity of this condition signifies the need for reporting all cases to facilitate future research and clinical management.
