{"pk":16552,"title":"Subchorionic Hemorrhage Appearing as Twin Gestation on Endovaginal Ultrasound","subtitle":null,"abstract":"This case study describes a pregnant patient with vaginal bleeding who had a bedside endovaginal ultrasound in the emergency department (ED). The emergency physician identified a live intra-uterine pregnancy (IUP) with another structure that appeared to be a second gestational sac. The patient subsequently had an endovaginal ultrasound in the radiology department 46 minutes later. The attending radiologist described one live IUP and a subchorionic hemorrhage. Comparison of the ED and radiology ultrasound showed that the second structure, identified as a subchorionic hemorrhage, had significantly decreased in size. Endovaginal ultrasound in the evaluation of possible ectopic pregnancy is a useful bedside tool in the ED. We discuss a pitfall that can occur with endocavitary ultrasound when a twin gestation is presumed.","language":"en","license":{"name":"none","short_name":"none","text":"","url":"http://google.com"},"keywords":[{"word":"subchorionic hemorrhage"},{"word":"ultrasound"},{"word":"vaginal bleeding"},{"word":"bedside ultrasound"},{"word":"endovaginal ultrasound"}],"section":"Article","is_remote":true,"remote_url":"https://escholarship.org/uc/item/3w57h9nz","frozenauthors":[{"first_name":"Andy","middle_name":"","last_name":"Kahn","name_suffix":"","institution":"Baylor Medical Center at Garland","department":"None"},{"first_name":"Amy","middle_name":"L","last_name":"Kahn","name_suffix":"","institution":"Baylor Medical Center at Garland","department":"None"},{"first_name":"J","middle_name":"Christian","last_name":"Fox","name_suffix":"","institution":"University of California, Irvine Medical Center, Department of Emergency Medicine","department":"None"},{"first_name":"Mark","middle_name":"","last_name":"Langdorf","name_suffix":"","institution":"University of California, Irvine Medical Center, Department of Emergency Medicine","department":"None"}],"date_submitted":"2007-10-13T07:00:00Z","date_accepted":"2007-10-13T07:00:00Z","date_published":"2008-05-10T07:00:00Z","render_galley":null,"galleys":[{"label":"","type":"pdf","path":"https://journalpub.escholarship.org/westjem/article/16552/galley/8373/download/"}]}
