Radiologic aspects of hepatic echinococcosis. Value of the intravenous viscerogram and computed tomography.

Over five years, 105 patients with hepatic echinococcosis were studied. Plain radiographs of the hepatic area yielded the correct diagnosis in 35% of patients. Intravenous viscerograms were diagnostic in all but 14 of the patients (an accuracy of 83%). Computed tomography was performed in 19 cases and proved the most efficient of the techniques--it was diagnostic in all 19 cases. The radiological signs of this entity are discussed.
