RationaleHepatic arteriovenous malformations (HAVMs) are a rare disorder reported in association with hereditary hemorrhagic telangiectasia (HHT), known as Rendu-Osler-Weber syndrome. HAVMs are usually detected in adulthood.Patient ConcernsA 29-year-old pregnant woman underwent a routine prenatal examination at 37 weeks of pregnancy.Diagnosis And InterventionsThere were fetal liver anomalies detected by prenatal ultrasonography and were managed. Furthermore, a hepatic mass was detected and was subsequently analyzed by fetal magnetic resonance imaging. There were no typical imaging findings in this case which was once misdiagnosed as a hepatoblastoma.OutcomesConsidering the massive hepatic lesion, labor induction was performed on a pregnant woman to avoid adverse maternal and fetal outcomes. Histopathological examination confirmed the diagnosis of HAVMs. Lesions detected by imaging were determined to be hemorrhagic and necrotic.LessonsPrenatal hepatic hemorrhage and necrosis due to an arteriovenous malformation are rare. The authors describe their observations and results.Copyright © 2023 the Author(s). Published by Wolters Kluwer Health, Inc.
