FIF can be a diagnostic dilemma due to its similarity to a teratoma, but identification of FIF is important for subsequent medical and surgical management. We compare two cases of fetal masses diagnosed on prenatal imaging that were later identified as FIF through further radiological, surgical, and pathologic evaluation. We use these cases to illustrate key pre- and postnatal features of FIF and highlight the benefits of prenatal detection and follow-up for postnatal management.<\/jats:p>","DOI":"10.3233\/npm-16101","type":"journal-article","created":{"date-parts":[[2017,8,25]],"date-time":"2017-08-25T13:38:08Z","timestamp":1503668288000},"page":"333-338","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":6,"title":["Impact of prenatal diagnosis of fetus-in-fetu"],"prefix":"10.1177","volume":"10","author":[{"given":"E.K.","family":"Sewell","sequence":"first","affiliation":[{"name":"Division of Neonatology, Children\u2019s National Health Systems, Washington, DC, USA"},{"name":"Depart of Pediatrics, The George Washington University School of Medicine and Health Sciences, Washington, DC, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"B.","family":"Massa-Buck","sequence":"additional","affiliation":[{"name":"Division of Neonatology, Children\u2019s National Health Systems, Washington, DC, USA"},{"name":"Depart of Pediatrics, The George Washington University School of Medicine and Health Sciences, Washington, DC, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"E.I.","family":"Rubio","sequence":"additional","affiliation":[{"name":"Division of Radiology, Children\u2019s National Health Systems, Washington, DC, USA"},{"name":"Department of Radiology, The George Washington University School of Medicine and Health Sciences, Washington, DC, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"A.N.","family":"Massaro","sequence":"additional","affiliation":[{"name":"Division of Neonatology, Children\u2019s National Health Systems, Washington, DC, USA"},{"name":"Division of Fetal Medicine, Children\u2019s National Health Systems, Washington, DC, USA"},{"name":"Depart of Pediatrics, The George Washington University School of Medicine and Health Sciences, Washington, DC, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"A.","family":"Badillo","sequence":"additional","affiliation":[{"name":"Division of General and Thoracic Surgery Children\u2019s National Health Systems, Washington, DC, USA"},{"name":"Department of Surgery, The George Washington University School of Medicine and Health Sciences, Washington, DC, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"E.","family":"Puscasiu","sequence":"additional","affiliation":[{"name":"Division of Pathology, Children\u2019s National Health Systems, Washington, DC, USA"},{"name":"Department of Pathology, The George Washington University School of Medicine and Health Sciences, Washington, DC, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"R.","family":"Broth","sequence":"additional","affiliation":[{"name":"Maternal Fetal Medicine, TLC Perinatal, Silver Spring, MD, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"T.","family":"Falika-King","sequence":"additional","affiliation":[{"name":"Department of Perinatology\/Maternal Fetal Medicine, Inova Fairfax Hospital, Fairfax, VA, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"B.","family":"Nies","sequence":"additional","affiliation":[{"name":"Department of Perinatology\/Maternal Fetal Medicine, Inova Fairfax Hospital, Fairfax, VA, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"A.","family":"Penn","sequence":"additional","affiliation":[{"name":"Division of Neonatology, Children\u2019s National Health Systems, Washington, DC, USA"},{"name":"Division of Fetal Medicine, Children\u2019s National Health Systems, Washington, DC, USA"},{"name":"Depart of Pediatrics, The George Washington University School of Medicine and Health Sciences, Washington, DC, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2017,8,23]]},"reference":[{"key":"ref001","doi-asserted-by":"publisher","DOI":"10.1007\/s00276-011-0868-9"},{"key":"ref002","doi-asserted-by":"publisher","DOI":"10.1097\/MD.0000000000001322"},{"key":"ref003","doi-asserted-by":"publisher","DOI":"10.1016\/j.ajog.2015.10.930"},{"key":"ref004","doi-asserted-by":"publisher","DOI":"10.1542\/peds.105.6.1335"},{"key":"ref005","doi-asserted-by":"publisher","DOI":"10.1007\/s00383-002-0943-8"},{"key":"ref006","doi-asserted-by":"publisher","DOI":"10.1186\/1471-2431-14-88"},{"key":"ref007","doi-asserted-by":"publisher","DOI":"10.1016\/S0022-3468(97)90112-3"},{"key":"ref008","doi-asserted-by":"crossref","unstructured":"HigginsKR, ColeyBD.
