Computed tomographic diagnosis of Echinococcus alveolaris.

CT was performed in seventeen cases of E. alveolaris of the liver, and two cases of E. alveolaris of the lung. The scans provided considerable detailed information which, when taken together, enabled a specific diagnosis of echinococcus infestation to be made in most cases. The extent of intra- and extrahepatic infiltration by E. alveolaris can be well defined by CT.
