ANSWER
Answer	Focal nodular hyperplasia
Comments	This case report describes a hepatic tumor that was incidentally discovered in a pediatric patient with no underlying liver disease. On color Doppler imaging, there were findings suggestive of a central stellate scar, and the corresponding area demonstrated high signal intensity on T2-weighted MRI. Furthermore, on contrast-enhanced MRI, the lesion, excluding the central scar, showed homogeneous enhancement during the arterial phase and persistent enhancement in the portal venous phase with no evidence of washout. An additional finding, though not presented in the primary text, was homogeneous high signal intensity in the hepatobiliary phase (sparing the central scar). All of these findings are characteristic of focal nodular hyperplasia.
