Here we present a second-trimester tubal ectopic pregnancy that was previously misdiagnosed as an intrauterine pregnancy on a first-trimester ultrasound. A 39-year-old gravida 1 para 0 woman at 15 weeks gestation presented with 10 days of progressive, severe abdominal pain, along with vaginal bleeding and intermittent vomiting for two months. She was ultimately found to have a ruptured left tubal ectopic pregnancy. Second-trimester ectopic pregnancies carry a significant maternal mortality risk. Even with the use of ultrasound, they are difficult to diagnose and present unique diagnostic challenges.<\/jats:p>","DOI":"10.5811\/cpcem.2019.1.40860","type":"journal-article","created":{"date-parts":[[2019,2,25]],"date-time":"2019-02-25T15:22:07Z","timestamp":1551108127000},"page":"62-64","source":"Crossref","is-referenced-by-count":8,"title":["Ruptured Tubal Ectopic Pregnancy at Fifteen Weeks Gestational Age"],"prefix":"10.5811","volume":"3","author":[{"given":"Justine","family":"Stremick","sequence":"first","affiliation":[{"name":"Fort Belvoir Community Hospital, Department of Emergency Medicine, Fort Belvoir, Virginia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kyle","family":"Couperus","sequence":"additional","affiliation":[{"name":"Madigan Army Medical Center, Department of Emergency Medicine, Joint Base Lewis-McChord, Washington"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Simeon","family":"Ashworth","sequence":"additional","affiliation":[{"name":"Madigan Army Medical Center, Department of Emergency Medicine, Joint Base Lewis-McChord, Washington"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"29705","published-online":{"date-parts":[[2019,1,29]]},"reference":[{"key":"ref0","doi-asserted-by":"crossref","unstructured":"Taran F, Kagan K, H\u00fcbner M et al.
