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).
