While many cases resolve, transient abnormal myelopoiesis may lead to significant morbidity and mortality in a small percentage of patients. This condition may present a diagnostic challenge for physicians and currently there is only limited data on effective treatments, particularly with low blast percent transient abnormal myelopoiesis. We present a case of a neonate with trisomy 21 and multiple congenital anomalies who consequently developed hepatic failure with evidence of non-cirrhotic portal hypertension likely due to transient abnormal myelopoiesis. This clinical scenario highlights the need for additional evaluation for transient abnormal myelopoiesis associated hepatic disorder and possibly hepatic sinusoidal occlusive syndrome among trisomy 21 neonates particularly with low blast percentage.<\/jats:p>","DOI":"10.3233\/npm-230094","type":"journal-article","created":{"date-parts":[[2023,12,8]],"date-time":"2023-12-08T13:46:49Z","timestamp":1702043209000},"page":"735-740","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":0,"title":["A rare case of hepatic sinusoidal occlusive syndrome in a premature neonate with trisomy 21"],"prefix":"10.1177","volume":"16","author":[{"given":"A.J.","family":"Alenchery","sequence":"first","affiliation":[{"name":"Department of Pediatric Gastroenterology, Hepatology and Nutrition, Cleveland Clinic Children\u2019s, Cleveland, OH, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"N.K.","family":"Yeaney","sequence":"additional","affiliation":[{"name":"Neonatal Director, Fetal Care Center, Cleveland Clinic Children\u2019s, Cleveland, OH, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"C.B.","family":"Chen","sequence":"additional","affiliation":[{"name":"Department of Pediatric Gastroenterology, Hepatology and Nutrition, Cleveland Clinic Children\u2019s, Cleveland, OH, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"R.","family":"Talati","sequence":"additional","affiliation":[{"name":"Department of Pediatric Hematology\/Oncology\/Bone Marrow Transplantation, Cleveland Clinic, Cleveland, OH, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"E.","family":"Vogelius","sequence":"additional","affiliation":[{"name":"Section Head, Pediatric Radiology, Imaging Institute, Cleveland Clinic, Cleveland, OH, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"C.","family":"Tan","sequence":"additional","affiliation":[{"name":"Department of Anatomic Pathology, Cleveland Clinic, Cleveland, OH, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"K.","family":"Radhakrishnan","sequence":"additional","affiliation":[{"name":"Department of Pediatric Gastroenterology, Hepatology and Nutrition, Cleveland Clinic Children\u2019s, Cleveland, OH, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2023,12,7]]},"reference":[{"key":"ref001","unstructured":"CDC.
