A serum alpha-fetoprotein level at birth was 373,170 ng/mL. Postnatal magnetic resonance imaging confirmed a mass in the right lobe of the liver, and a percutaneous core biopsy revealed an epithelial type hepatoblastoma with predominantly embryonal histology. Methylation testing revealed hypomethylation at imprinting center 2, consistent with a diagnosis of Beckwith-Wiedemann syndrome. This case suggests that Beckwith-Wiedemann syndrome testing should be considered in all patients with hepatoblastoma, even in the absence of other phenotypic stigmata.
