Sonographic Mimic of Ovarian Ectopic Pregnancy by Point-of-Care Ultrasound

The detection of ectopic pregnancy (EP) by point-of-care ultrasound has become an integral competency of emergency medicine practice. Clinical algorithms usually include a female of childbearing age, positive urine or serum human chorionic gonadotropin (hCG) test, and an ultrasound evaluation to assess the presence or absence of intrauterine pregnancy. This case report illustrates incidental findings observed during focused assessment with sonography in trauma (FAST examination), which initially suggested an intra-ovarian EP. The clinical images and interpretation are subsequently discussed. This case is important to the practice of general emergency medicine in that it illustrates the importance of contextual interpretation, management, and recognition of normal anatomical features and incidental findings commonly encountered during point-of-care sonography.
