title: Sonographic demonstration of heterotopic pregnancy: report of two cases.
abstract: We described two patients with heterotopic pregnancy. In one patient the transabdominal sonographic findings were non-specific and laparoscopy was required for diagnosis. In the second patient transabdominal sonographic findings suggested a diagnosis of heterotopic pregnancy. Endovaginal sonography confirmed this by allowing visualization of the live extrauterine gestation.
