Ultrasound represents an important contribution to the diagnosis of hepatosplenic mansonic schistosomiasis. Abnormalities such as hyperechoic fibrotic bands along the portal vessels, volumetric reduction of the right hepatic lobe, enlargement of the left lobe, perivesicular fibrotic thickening and splenomegaly can be recognized. Moreover, the hemodynamic status of the portal venous system may also be evaluated by Doppler analysis, including the identification of collateral veins and portosystemic venous shunts. In endemic areas, ultrasound is of great value in the identification of hepatosplenomegaly, allowing follow-up of patients under clinical treatment. This review presents the ultrasonographic and Doppler features of hepatosplenic schistosomiasis. The relationship between these findings and the clinical and pathological characteristics of this disease are also discussed.
