Abstract
Diagnosis of liver infestation by Echinococcus alveolaris EA is based on serological and radiological findings In this report we present a 15yearold girl with atypical hepatic EA infestation showing central punctate calcifications and contrast enhancement on the portal and late phases of CT and MRI CT showed a hypodense mass involving more than half of the liver with prominent central calcifications MRI revealed hypointense signal of the infiltrative mass on both T1 and T2weighted images Contrast enhancement is a unique finding in hepatic EA infestation that may cause difficulties with diagnosis MRI may provide invaluable information in the diagnosis of EA infestation of the liver either by disclosing the infiltrative pattern of infestation without significant effect to vascular structures or by the signal characteristics
