Abstract

The purpose of this chapter is to familiarize the radiologist with various obstetric emergencies which can be encountered during early pregnancy to ensure their correct diagnoses and facilitate the prompt initiation of appropriate management. We will provide an algorithmic approach toward the assessment of early pregnancy and highlight the characteristic and pathognomonic findings that will improve pattern recognition in distinguishing pathological processes encountered in the first trimester. The initial discussion offers a detailed review of embryonic development and normal imaging findings in early pregnancy, paired with expected laboratory and physical examination findings. This is followed by a detailed review of pathological processes, including pregnancy of unknown location (PUL), early pregnancy failures, ectopic pregnancy of different pelvic locations, retained products of conception and associated complications, gestational trophoblastic disease, failed intrauterine devices and tubal ligation, and early pregnancy infections. In the first trimester, diagnostic ultrasound (US) is the primary imaging modality utilized for evaluation, and therefore, the discussion will predominantly involve sonographic features of pathological processes, with computed tomography (CT) or magnetic resonance imaging (MRI) correlation when applicable (Expert Panel on Women’s Imaging et al., J Am Coll Radiol 15:S69–S77, 2018).
