This educational abstract is intended to review normal endometrial findings in the nonpregnant pre-menopausal, pregnant, and post-menopausal patient with an emphasis on ultrasound (US). It is important to be familiar with the expected normal imaging findings of pre-menopause, the menstrual cycle, pregnancy, and post-menopause to recognize pathology. As the breadth of pregnancy imaging is vast, we will focus on select first trimester pregnancy topics, such as a normal gestational sac, yolk sac, and embryo.

Educational Goals / Teaching Points
Using this foundation of normals, the imaging findings of endometrial pathology will be discussed utilizing multiple imaging modalities including 3D US, CT, MRI, and saline infusion sonohysterogram (HSG). Case examples of key diagnoses will be provided using this multimodality approach.

Key Anatomic/Physiologic Issues and Imaging Findings/Techniques
Endometrial pathology to be highlighted includes endometrial cancer, polyps, hyperplasia, fibroids, and the effects of tamoxifen. The gestational related pathologic findings of molar pregnancy, failed pregnancy, retained products of conception, and pseudogestational sac with ectopic pregnancies will also be discussed.

When possible, pathologic proven cases will be included. A few key diagnostic dilemmas will be discussed and imaging pearls shared. The presentation will conclude with a quiz of what the reader learned.
