Hepatic nodular hyperplasia in a boy with Alagille syndrome: CT and MR appearances.
A boy with Alagille syndrome complicated by hepatic nodular hyperplasia (HNH) is reported. During pre-transplantation evaluation, CT and MRI revealed a large hepatic lesion with multiple small nodular lesions. Angiography demonstrated a large hypervascular lesion and CT arterial portography (CTAP) showed a portal perfusion defect corresponding to the lesion. CTAP also revealed large portal vein branches running through the lesion. Although hepatocellular carcinoma is known to accompany Alagille syndrome, HNH should also be considered when large vessels running through the lesion are demonstrated.
