The role of sonography in the diagnosis of Echinococcus alveolaris

Abdominal sonography and computed tomography were performed in eleven patients with operatively and histologically proven Echinococcus alveolaris of the liver and the detailed appearances were compared. Sonography is a useful screening method in the assessment of E. alveolaris, but its previous importance is being gradually superseded by computed tomography, which is capable of providing more detailed information in the diagnosis of Echinococcus infestation.
