RESUMEN
The aim of our study was to assess the role of ultrasonography in patients with chronic liver diseases in discriminating between schistosomiasis and viral hepatitis infections in Egypt, an area where these infections are endemic. We assessed 114 patients with chronic liver disease, clinically, ultrasonographically, biochemically, virologically, parasitologically and by liver biopsy. According to histological diagnosis; 7.9% of patients had portal fibrosis, 43% chronic hepatitis, 47.4% cirrhosis and 1.8% hepatic malignancies. Patients with cirrhosis 44 [49.4%] of them had pure HCV infection. The longitudinal diameter of the spleen was significantly higher in patients with cirrhosis- virus related liver disease than those with pure schistosomiasis, while no significant differences were found in the degree of periportal thickening between the two groups. This study shows that ultrasonography alone can not be used as a screening procedure to discriminate between schistosomiasis and viral hepatitis infections in areas where these infections are highly associated, such as in Egypt
