Presentation This is the ultrasound scan of the liver in a 39-year-old woman with right upper quadrant pain.
 
 
 
Caption: Oblique scan of the right lobe of liver
Description: A well-defined rounded mass that is similar in echogenicity to the normal parenchyma is seen in the right lobe of the liver. The center of the mass demonstrates a subtle linear hyperechoic area. This could represent a central scar [as seen in focal nodular hyperplasia]
 
 
 
Caption: Transverse color Doppler scan of the mass
Description: The mass displays central vascularity in the region of the linear scar.
 
 
 
Caption: Sagittal color Doppler scan of the mass
Description: This is another view of the mass demonstrating internal vascualrity.
 
 
 
Caption: Spectral waveform analysis of the mass
Description: An arterial waveform is recorded from the vessel coursing through the mass.
 
Differential Diagnosis Focal nodular hyperplasia, hemangioma, hepatic adenoma
 
Final Diagnosis Focal nodular hyperplasia in the liver
 
Follow Up An MRI was performed which confirmed the ultrasound findings.
