Does primary omental pregnancy exist?
Omental pregnancy is a rare form of abdominal pregnancy. In the 5 previously reported cases, primary implantation of the embryo to the omentum has been proposed as its etiology. We present a new case of omental pregnancy in a 31-year-old woman presenting with symptoms of ectopic pregnancy. After careful review of our case and the published literature in view of the accepted definition of primary abdominal pregnancy, we conclude that all reported instances of omental pregnancy are secondary and probably follow tubal or ovarian pregnancy abortion.
