Ultrasonographic follow-up of involuting placenta in advanced abdominal pregnancy diagnosed by magnetic resonance imaging

We successfully treated a case of advanced abdominal pregnancy which was diagnosed with ultrasonography and magnetic resonance imaging in a woman of 20th week of pregnancy who did not receive any prenatal care. It is advisable to leave the placenta in situ because removing the placenta may be associated with severe hemorrhage. Furthermore, identifi cation of uterine wall around the fetus and the placenta is very important in diagnosing abdominal pregnancy.
