ABSTRACT The differential diagnosis in a pregnant patient who presents with pain and bleeding in the first trimester includes normal early pregnancy, spontaneous abortion, molar pregnancy, and ectopic pregnancy. Knowledge of the sonographic appearance of these entities is helpful at arriving at the correct diagnosis. When no intrauterine pregnancy is visualized, careful attention to the adnexa is crucial for finding an extraovarian mass, since the fallopian tube is the most common location for ectopic pregnancy. This review describes and illustrates the sonographic findings of ectopic pregnancy.

    ABSTRACT: OBJECTIVE. Although ultrasound is the primary modality used in the diagnosis of ectopic pregnancy, various forms of this condition and their complications may occasionally be further evaluated with MRI or may be incidentally detected on CT or MRI when an alternative diagnosis is suspected. CONCLUSION. Various types of ectopic pregnancy have characteristic imaging features. Radiologists should be familiar with these features and should always consider the possibility of ectopic pregnancy in the setting of hemoperitoneum or a pelvic mass in a woman of child-bearing age. Familiarity with the typical CT and MRI appearances of various forms of ectopic pregnancy facilitates prompt and accurate diagnosis and treatment.

    ABSTRACT: Ectopic pregnancies occur in approximately 1.4% of all pregnancies and account for 15% of pregnancy-related deaths. Considering the high degree of mortality, recognizing an ectopic pregnancy is important. Signs and symptoms of an ectopic pregnancy are nonspecific and include pain, vaginal bleeding, and an adnexal mass. Therefore, imaging can play a critical role in diagnosis. There are different types of ectopic pregnancies, which are tubal, cornual, cesarean scar, cervical, heterotopic, abdominal, and ovarian. Initial imaging evaluation of pregnant patients with pelvic symptoms is by ultrasonography, transabdominal, transvaginal or both. We review the sonographic appearance of different types of ectopic pregnancies that will aid in accurate and prompt diagnosis.

    ABSTRACT: The terms ‘cornual,’ ‘interstitial,’ and ‘angular’ pregnancies are used inconsistently in the literature. Some sources use ‘interstitial’ and ‘cornual’ synonymously, while others reserve ‘cornual’ for gestations in bicornuate or septate uteri; others distinguish interstitial from angular pregnancy, while in practice many physicians are unfamiliar with the latter designation. This article aims to clarify the terms and review the literature with respect to diagnosis and prognosis, with attention to the potential roles of 3D ultrasound and MRI.
