We report on a case of a 19-month-old girl whose plain abdominal radiograph, ultrasonography, and computed tomography scan revealed a mass in which the contents favor a fetus in fetu rather than a teratoma. The noncalcified vertebral column invisible on the radiographs was identified by the pathologist; therefore, the nonvisualization of the vertebral axis on radiography or on computed tomography scan does not exclude the diagnosis of fetus in fetu.<\/jats:p>","DOI":"10.1542\/peds.105.6.1335","type":"journal-article","created":{"date-parts":[[2004,8,13]],"date-time":"2004-08-13T23:50:41Z","timestamp":1092441041000},"page":"1335-1344","source":"Crossref","is-referenced-by-count":133,"title":["Fetus In Fetu: A Case Report and Literature Review"],"prefix":"10.1542","volume":"105","author":[{"given":"Christine Caroline","family":"Hoeffel","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Khoang Quy","family":"Nguyen","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hai Thanh","family":"Phan","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Nghia Hieu","family":"Truong","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Trung Sao","family":"Nguyen","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Trai Thanh","family":"Tran","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Paul","family":"Fornes","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"417","published-online":{"date-parts":[[2000,6,1]]},"reference":[{"key":"2021121010213116300_B1","first-page":"319","article-title":"Twin fetuses in fetu and a review of the literature.","volume":"45","author":"Gu\u0308rses","year":"1990","journal-title":"Z Kinderchir."},{"key":"2021121010213116300_B2","first-page":"1019","article-title":"Foetus in foetu surre\u0301nalien: un cas e\u0301voque\u0301 par l'e\u0301chographie pre\u0301natale.","volume":"19","author":"Chitrit","year":"1990","journal-title":"J Gyne\u0301col Obste\u0301t Biol Reprod Paris."},{"key":"2021121010213116300_B3","first-page":"815","article-title":"Fetal inclusion cysts, report of case with discussion.","volume":"48","author":"Ford","year":"1949","journal-title":"Wis Med J."},{"key":"2021121010213116300_B4","first-page":"840","article-title":"Operativ entfernter Fo\u0308tus in Fo\u0308to.","volume":"66","author":"Haberer Von","year":"1939","journal-title":"Zentralblatt Chir."},{"key":"2021121010213116300_B5","doi-asserted-by":"crossref","first-page":"627","DOI":"10.1002\/path.1700720230","article-title":"Intra-abdominal f\u0153tus in fetu.","volume":"72","author":"Lord","year":"1956","journal-title":"J Pathol Bacteriol."},{"key":"2021121010213116300_B6","doi-asserted-by":"crossref","first-page":"732","DOI":"10.1136\/bmj.2.4531.732","article-title":"Endocyme foetus in Fiji infant.","volume":"2","author":"Maxwell","year":"1947","journal-title":"Br Med J."},{"key":"2021121010213116300_B7","first-page":"140","article-title":"Studies on tumour formation; kidney in a teratoma.","volume":"84","author":"Nicholson","year":"1934","journal-title":"Guy's Hosp Rep."},{"key":"2021121010213116300_B8","doi-asserted-by":"crossref","first-page":"1016","DOI":"10.5694\/j.1326-5377.1969.tb49866.x","article-title":"Foetus-in-foetu.","volume":"1","author":"Grant","year":"1969","journal-title":"Med J Aust."},{"key":"2021121010213116300_B9","doi-asserted-by":"crossref","first-page":"1432","DOI":"10.1016\/S0022-3468(98)90029-X","article-title":"Fetus-in-fetu: a case report and review of the literature.","volume":"33","author":"Thakral","year":"1998","journal-title":"J Pediatr Surg."},{"key":"2021121010213116300_B10","doi-asserted-by":"crossref","first-page":"146","DOI":"10.1259\/0007-1285-47-554-146","article-title":"Fetus in fetu.","volume":"47","author":"Tada","year":"1974","journal-title":"Br J Radiol."},{"key":"2021121010213116300_B11","doi-asserted-by":"crossref","first-page":"845","DOI":"10.3171\/jns.1982.56.6.0845","article-title":"Intraventricular fetus-in-fetu.
