Ultrasound features included a constriction ring around the external base of the developing skull and an enlarged globular head, resembling a Turkish turban, with large cystic spaces replacing the brain. This constellation of findings was noted in 3 first\u2010trimester fetuses. In 2 of them, it was possible to identify the amniotic membrane attached to the constriction ring. One case presented with anencephaly and fetal demise at 16\u2009weeks. The other 2 women terminated the pregnancies and aborted anencephalic fetuses. This subtype of the acrania\u2010anencephaly sequence could represent an earlier segmental rupture of the amnion, which subsequently entraps the developing fetal skull.<\/jats:p>","DOI":"10.1002\/jum.15161","type":"journal-article","created":{"date-parts":[[2019,11,9]],"date-time":"2019-11-09T10:59:10Z","timestamp":1573297150000},"page":"829-832","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":8,"title":["An Unusual First\u2010Trimester Ultrasound Presentation of the Acrania\u2010Anencephaly Sequence"],"prefix":"10.1002","volume":"39","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-3856-574X","authenticated-orcid":false,"given":"Waldo","family":"Sepulveda","sequence":"first","affiliation":[{"name":"Fetal Imaging Unit FETALMED\u2013Maternal\u2010Fetal Diagnostic Center  Santiago Chile"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Francisco","family":"De La Maza","sequence":"additional","affiliation":[{"name":"Ultrasound Unit Teachers\u2019 Hospital  Santiago Chile"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Simon","family":"Meagher","sequence":"additional","affiliation":[{"name":"Monash Ultrasound for Women Monash University  Melbourne Victoria Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2019,11,9]]},"reference":[{"key":"e_1_2_5_2_1","first-page":"117","volume-title":"Fetology: Diagnosis and Management of the Fetal Patient","author":"Bianchi DW","year":"2010"},{"key":"e_1_2_5_3_1","first-page":"23","article-title":"The birth of a monstrous child throughout history: the example of anencephaly between the Egyptian new empire and the 21st century","volume":"26","author":"Fischer JL","year":"2014","journal-title":"Med Secoli"},{"key":"e_1_2_5_4_1","doi-asserted-by":"publisher","DOI":"10.2214\/ajr.139.1.181"},{"key":"e_1_2_5_5_1","doi-asserted-by":"publisher","DOI":"10.1007\/BF00428230"},{"key":"e_1_2_5_6_1","doi-asserted-by":"publisher","DOI":"10.1002\/(SICI)1520-6661(199607\/08)5:4<182::AID-MFM4>3.0.CO;2-G"},{"key":"e_1_2_5_7_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0002-9378(97)70610-0"},{"key":"e_1_2_5_8_1","doi-asserted-by":"publisher","DOI":"10.1046\/j.1469-0705.1997.09010014.x"},{"key":"e_1_2_5_9_1","doi-asserted-by":"publisher","DOI":"10.7863\/jum.2003.22.10.1075"},{"key":"e_1_2_5_10_1","doi-asserted-by":"publisher","DOI":"10.15557\/JoU.2018.0035"},{"key":"e_1_2_5_11_1","doi-asserted-by":"publisher","DOI":"10.1046\/j.1469-0705.1999.13030196.x"},{"key":"e_1_2_5_12_1","doi-asserted-by":"publisher","DOI":"10.1046\/j.1469-0705.1996.07040239.x"},{"key":"e_1_2_5_13_1","doi-asserted-by":"publisher","DOI":"10.1056\/NEJM199911113412006"},{"key":"e_1_2_5_14_1","doi-asserted-by":"publisher","DOI":"10.1016\/S1474-4422(13)70110-8"},{"key":"e_1_2_5_15_1","doi-asserted-by":"publisher","DOI":"10.1146\/annurev-neuro-062012-170354"}],"container-title":["Journal of Ultrasound in Medicine"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/pdf\/10.1002\/jum.15161","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/full-xml\/10.1002\/jum.15161","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/pdf\/10.1002\/jum.15161","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2023,9,6]],"date-time":"2023-09-06T20:09:30Z","timestamp":1694030970000},"score":1,"resource":{"primary":{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/10.1002\/jum.15161"}},"subtitle":["The \u201cTurkish Turban\u201d Sign"],"short-title":[],"issued":{"date-parts":[[2019,11,9]]},"references-count":14,"journal-issue":{"issue":"4","published-print":{"date-parts":[[2020,4]]}},"alternative-id":["10.1002\/jum.15161"],"URL":"https:\/\/doi.org\/10.1002\/jum.15161","archive":["Portico"],"relation":{},"ISSN":["0278-4297","1550-9613"],"issn-type":[{"value":"0278-4297","type":"print"},{"value":"1550-9613","type":"electronic"}],"subject":[],"published":{"date-parts":[[2019,11,9]]},"assertion":[{"value":"2019-09-08","order":0,"name":"received","label":"Received","group":{"name":"publication_history","label":"Publication History"}},{"value":"2019-10-04","order":1,"name":"accepted","label":"Accepted","group":{"name":"publication_history","label":"Publication History"}},{"value":"2019-11-09","order":2,"name":"published","label":"Published","group":{"name":"publication_history","label":"Publication History"}}]}}
