【Introduction】 Characteristics of the B-mode ultrasound findings of the liver parenchyma, like a mesh-work pattern observed in HBV-related liver cirrhosis（LC-B）, are clinically useful in diagnosing the liver diseases, even though the frequency of those findings are not so high. Recently, we have experienced a characteristic wire-netting appearance similar to the mesh-work pattern of the LC-B in patients with alcoholic liver cirrhosis（ALC）or with primary biliary cirrhosis（PBC）. And, the findings may be of a help for diagnosing those liver diseases. The aims of this study were to assess the significance of the wire-netting appearance within the liver parenchyma in patients with ALC or PBC, and to clarify the usefulness of the findings in diagnosing those liver diseases. 【Materials and methods】 The materials of 105 patients diagnosing PBC who visited our hospital from April 2010 to March 2015 and 76 patients of ALC,32patients of LC-B,182patients of HCV-related liver cirrhosis（LC-C）. All patients underwent an ultrasound examination. 【Result】 PBC: 30 patients（28.6％）showed meshwork like appearance. ALC: 8 patients（10％）showed meshwork like appearance LC-B: 9 patients（28.1％）showed meshwork like appearance. LC-C: 3 patients showed meshwork like appearance. 【Conclusions】 Our results suggest that the ultrasonographic wire-netting appearance observed within the liver parenchyma may be an important diagnostic finding in ALC or PBC.
