Maternal malabsorption, such as in Crohn\u2019s disease, may impair transplacental vitamin K transfer, increasing neonatal coagulopathy risk. Case Report: A 32-year-old woman with Crohn\u2019s disease and prior bowel resections delivered at 35+3 weeks due to preeclampsia and fetal distress. Her infant developed severe coagulopathy and a hemorrhagic thymic mass. Laboratory results showed elevated INR and PIVKA-II, which improved with vitamin K and plasma. The mother experienced postpartum hemorrhage and coagulopathy, requiring transfusions, embolization, and vitamin K. Both recovered with treatment. At 13 months, the infant showed only mild left-hand weakness and normal development. Conclusion: This case highlights the risk of neonatal VKDB and maternal bleeding due to undiagnosed maternal vitamin K deficiency. Screening and supplementation should be considered in pregnancies affected by malabsorptive disorders like Crohn\u2019s disease.<\/jats:p>","DOI":"10.1159\/000547451","type":"journal-article","created":{"date-parts":[[2025,7,24]],"date-time":"2025-07-24T16:02:40Z","timestamp":1753372960000},"page":"673-676","source":"Crossref","is-referenced-by-count":0,"title":["Neonatal Thymic Hemorrhage Secondary to Vitamin K Deficiency: A Case Report"],"prefix":"10.1159","volume":"122","author":[{"given":"Nicole","family":"Asdell","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Cecilie","family":"Halling","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Susan M.","family":"Lopata","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sheria D.","family":"Wilson","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Shamlal","family":"Mangray","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Zachary J.","family":"Farmer","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"127","published-online":{"date-parts":[[2025,7,24]]},"reference":[{"key":"ref1","doi-asserted-by":"publisher","DOI":"10.1542\/pir.2019-0146"},{"key":"ref2","doi-asserted-by":"publisher","DOI":"10.1259\/bjr.70.830.9135451"},{"key":"ref3","doi-asserted-by":"publisher","DOI":"10.1186\/s13052-015-0196-5"},{"key":"ref4","doi-asserted-by":"publisher","DOI":"10.1038\/jp.2014.64"},{"key":"ref5","doi-asserted-by":"publisher","DOI":"10.1016\/s0022-3468(96)90263-8"},{"key":"ref6","doi-asserted-by":"publisher","DOI":"10.1053\/j.gastro.2015.12.003"},{"key":"ref7","doi-asserted-by":"publisher","DOI":"10.1038\/s41598-018-29616-y"},{"key":"ref8","doi-asserted-by":"publisher","DOI":"10.3109\/14767058.2012.657273"}],"container-title":["Neonatology"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/karger.com\/article-pdf\/doi\/10.1159\/000547451","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,12,1]],"date-time":"2025-12-01T17:11:29Z","timestamp":1764609089000},"score":1,"resource":{"primary":{"URL":"https:\/\/karger.com\/article\/doi\/10.1159\/000547451"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2025,7,24]]},"references-count":8,"journal-issue":{"issue":"6","published-online":{"date-parts":[[2025,12,1]]},"published-print":{"date-parts":[[2025,12,3]]}},"URL":"https:\/\/doi.org\/10.1159\/000547451","archive":["Portico"],"relation":{"is-supplemented-by":[{"id-type":"doi","id":"10.6084\/m9.figshare.29617898","asserted-by":"subject"}]},"ISSN":["1661-7800","1661-7819"],"issn-type":[{"type":"print","value":"1661-7800"},{"type":"electronic","value":"1661-7819"}],"subject":[],"published":{"date-parts":[[2025,7,24]]}}}
