A case with regenerative nodule demonstrated by ultrasound examination was reported.<BR>Hepatocellular carcinoma in the left lobe of the liver was pointed out in a 55-year-old male with liver cirrhosis.<BR>In addition, the hypoechoic nodule (3cm in diameter) was demonstrated in the posterosuperior area of the right lobe. As this lesion had no tumor stain in angiogram and no defect in radionuclide liver scintigraphy, we suspected this lesion to be a regenerative nodule and it was subsequently comfirmed by wedge resection during left lateral segmentectomy for hepatocellular carcinoma.<BR>Recently, ultrasound has been primarily used for screening of hepatocellular carcinoma in patients with liver cirrhosis. We think when a less echogenic nodule is demostrated by ultrasound in patient with liver cirrhosis, the possibility of regenerative nodule shoud be always taken into consideration.
