There are no established sonographic criteria to differentiate it from abdominal pregnancy; however, differences in their medical management make this distinction important. We report a case of a 14\u2010week 5\u2010day tubal pregnancy that presented near rupture. Sonography demonstrated many overlapping features with abdominal pregnancy. In addition, the extrauterine gestational sac was rounded and well defined and the placenta was crescent\u2010shaped. We propose that these sonographic features represent a second\u2010trimester tubal pregnancy rather than an abdominal pregnancy. \u00a9 2013 Wiley Periodicals, Inc. <jats:italic>J Clin Ultrasound<\/jats:italic> <jats:bold>42<\/jats:bold>:162\u2013168, 2014<\/jats:p>","DOI":"10.1002\/jcu.22076","type":"journal-article","created":{"date-parts":[[2013,8,2]],"date-time":"2013-08-02T09:52:32Z","timestamp":1375437152000},"page":"162-168","source":"Crossref","is-referenced-by-count":7,"title":["The usefulness of gestational sac and placental sonographic morphology in differentiating between second\u2010trimester tubal and abdominal pregnancy: Case report and a review of literature"],"prefix":"10.1002","volume":"42","author":[{"given":"Joseph","family":"Liu","sequence":"first","affiliation":[{"name":"Department of Radiology Wayne State University\/Detroit Medical Center 4201 St. Antoine St., DRH 3L\u20108, Detroit, MI 48201"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ambereen","family":"Khan","sequence":"additional","affiliation":[{"name":"Department of Radiology Wayne State University\/Detroit Medical Center 4201 St. Antoine St., DRH 3L\u20108, Detroit, MI 48201"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Samuel","family":"Johnson","sequence":"additional","affiliation":[{"name":"Department of Radiology Wayne State University\/Detroit Medical Center 4201 St. Antoine St., DRH 3L\u20108, Detroit, MI 48201"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Cheryl","family":"Grigorian","sequence":"additional","affiliation":[{"name":"Department of Radiology Wayne State University\/Detroit Medical Center 4201 St. Antoine St., DRH 3L\u20108, Detroit, MI 48201"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Tao","family":"Li","sequence":"additional","affiliation":[{"name":"Department of Radiology VA Puget Sound Health Care System, University of Washington Mail Box 358280 S\u2010114\/Radiology 1660 South Columbian Way Seattle WA 98108"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2013,8,2]]},"reference":[{"key":"e_1_2_5_2_1","doi-asserted-by":"publisher","DOI":"10.1093\/humrep\/17.12.3224"},{"key":"e_1_2_5_3_1","doi-asserted-by":"publisher","DOI":"10.1016\/0002-9378(55)90111-3"},{"key":"e_1_2_5_4_1","first-page":"209","article-title":"Tubal pregnancy carried to the 27th week [in Croatian]","volume":"29","author":"Hodek B","year":"1989","journal-title":"Jugosl Ginekol Perinatol"},{"key":"e_1_2_5_5_1","first-page":"915","article-title":"Midtrimester tubal pregnancy with markedly elevated maternal serum alpha\u2010fetoprotein.
