Figure 1 Focal nodular hyperplasia in a 2-year-old boy. A: The lesion was hypodense on pre-contrast computed tomography scan; B: The lesion was significantly enhanced in the arterial phase with enlarged feeding arteries (arrows); C: The lesion was hyperdense in the portal vein phase with hypodense central scar (arrows) and fibrous septa; D: The lesion was isodense in the equilibrium phase, and the scar shows delayed enhanced; E: Computed tomography angiography (CTA) in the arterial phase showed that the enlarged feeding artery was distorted with a spoke-wheel shaped blood supply (arrows); F: CTA in the portal vein phase showed the draining vessels directly into the hepatic vein (arrows).

Figure 2 Focal nodular hyperplasia in a 16-year-old boy. A: The lesion was hypodense on pre-contrast computed tomography scan, and central scar with much lower density were identified (arrows); B: The lesion was significantly enhanced in the arterial phase with enlarged feeding arteries penetrating into the central scar (arrows); C: The lesion was slightly hyperdense in the portal vein phase; D: The lesion was isodense in the equilibrium phase with delayed enhancement of the central scar; E: Computed tomography angiography (CTA) in the arterial phase showed that the enlarged feeding arteries were distorted, and exhibited a spoke-wheel shaped blood supply (arrows); F: CTA in the portal vein phase showed the draining hepatic vein (arrows).

Figure 3 Focal nodular hyperplasia in a 14-year-old girl. A: The lesion was hypodense on pre-contrast computed tomography image; B, C: The lesion was significantly enhanced in the arterial phase with hypodense fibrous septa; D: The lesion was isodense in the portal vein phase; E: Immunohistochemical staining of CD34 revealed the abnormal blood vessels within fibrous septa (× 100); F: Computed tomography angiography in the arterial phase showed that a spoke-wheel shaped blood supply of the focal nodular hyperplasia (arrow).
