Focal nodular hyperplasia coexistent with hepatoblastoma in a 36-d-old infant

Figure 1 Computed tomography findings. A: Non-contrast computed tomography (CT) of the liver showed a slightly hypo-dense mass in the right lobe of the liver (arrow) with a hypo-dense central star-like scar (asterisk); B: Contrast-enhanced CT of the liver in the portal venous phase showed inhomogeneous and intense enhancement of the mass (arrow), with the central star-like scar (asterisk); C: Histopathology showed typical focal nodular hyperplasia, with hepatocytic nodules separated by bands of fibrous tissue (HE stain, original magnification × 50); D: Foci of hepatoblastoma showed epithelioid tumor cells separated by proliferated fibrous tissue (HE stain, original magnification × 100).
