Fig. 3D —34-year-old man with asymptomatic rapidly enhancing hemangioma exhibiting discordance due to differences in timing. Contrast-enhanced sonography was performed after outside CT, which suggested focal nodular hyperplasia. Axial arterial phase CT image obtained 35 seconds after contrast administration shows uniformly enhanced mass. Diagnostic considerations include hemangioma and focal nodular hyperplasia. Mass exhibited sustained enhancement in portal venous phase on both sonogram and CT scan.
