Ultrasonographic diagnosis and follow-up of a special type of giant fetal hepatic hemangioma.

We present a case of giant fetal hepatic hemangioma to illustrate the impact of ultrasound monitoring on treatment outcomes. Prenatal ultrasound revealed cardiac enlargement, leading to a cesarean section. The neonate had multiple vascular anomalies, including hepatic artery-portal fistula, portal-hepatic venous fistula, and a giant arteriovenous fistula for the abnormal right internal thoracic artery with portal vein, causing progressive pulmonary hypertension. Postnatal embolization and propranolol treatment resulted in significant tumor shrinkage on ultrasonography and resolution by age 2 years. This report highlights the value of detailed prenatal ultrasound monitoring in guiding effective treatment and improving outcomes for giant fetal hepatic hemangioma, a rare but potentially life-threatening condition.
