Interstitial, angular, and cornual pregnancies and intrauterine pregnancies in an anomalous uterus are separate entities, and the impact of each condition on obstetric outcomes is completely different. However, there is considerable confusion in understanding and managing the natural course of each condition due to a lack of uniform terminology. The single most important factor for differentiating these types of pregnancies is to make an early diagnosis. The differences between interstitial, angular, and cornual pregnancies on 2-dimensional (2D) sonography are subtle. Although magnetic resonance imaging can be used to differentiate these conditions, it is not preferred as the initial assessment tool because of its limited availability and cost-effectiveness. Three-dimensional (3D) sonography has the advantage of providing views of the uterus that cannot be obtained with conventional 2D sonography. We describe 3 cases of interstitial, angular, and intrauterine pregnancies in a septate uterus that were clearly differentiated by 3D sonography. We demonstrate the differences in diagnostic imaging findings and emphasize the importance of 3D sonography in differentiating these entities.
间质部、角部和宫角妊娠以及子宫畸形中的宫内妊娠是不同的情况，每种情况对产科结局的影响完全不同。然而，由于缺乏统一的术语，在理解和处理每种情况的自然病程方面存在相当大的困惑。区分这些类型妊娠的最重要因素是早期诊断。二维（2D）超声检查中间质部、角部和宫角妊娠之间的差异很细微。虽然磁共振成像可用于区分这些情况，但由于其可用性有限和性价比不高，不作为首选的初始评估工具。三维（3D）超声检查的优势在于能够提供传统2D超声检查无法获得的子宫图像。我们描述了3例在纵隔子宫中的间质部、角部和宫内妊娠，通过3D超声检查得以清晰区分。我们展示了诊断成像结果的差异，并强调了3D超声检查在区分这些情况中的重要性。
