Hepatic tumors. Case 1. Multiple hepatic hemangiomas. Coronal T2-HASTE MRI (a) shows the multiple hyperintense hepatic lesions (white arrows). Observe the right hemihypertrophy in this newborn with Beckwith-Wiedemann syndrome (vertical arrows). Case 2. Hemangioendothelioma. Coronal (b) T2-HASTE MRI (27th week) shows a large and infiltrating mass arising from the left hepatic lobe with predominantly high signal intensity. Observe the signs of fetal congestive heart failure with marked hydrops fetalis (white block arrows). Case 3. Mesenchymal hamartoma. Axial T2-weighted image (c) shows a centrally located, hepatic hyperintense cystic mass with internal septations in this 10-week-old boy (same patient as in Fig. 5d, e). Case 4. Hepatoblastoma. Abdominal ultrasound (d) shows the large, heterogeneous mass in the right hepatic lobe of this 2-day-old girl
