Prenatal Ultrasound Diagnosis and Prognostic Analysis of Fetal Congenital Hepatic Hemangioma

While prenatal ultrasound manifestations of fetal CHH demonstrate considerable heterogeneity, features are commonly observed in our cohort. Definitive diagnosis can be achieved in most cases through multimodal imaging combining ultrasound with MRI or CT. While most fetuses with CHH have a favorable prognosis, large tumors may cause severe complications and adverse pregnancy outcomes, warranting regular surveillance. For neonates with small tumors or asymptomatic lesions, active observation is the primary management strategy; pharmacotherapy is indicated for rapidly enlarging or large tumors, with interventional or surgical interventions reserved for pharmacologically refractory cases.
