Author information

Department of Radiodiagnosis, Bangalore Medical College and Research Institute, Bangalore, India.


Hydatid disease is a parasitic infection caused by Echinococcus granulosus and Echinococcus multilocularis. It is common in endemic regions and can demonstrate a variety of imaging features that differ according to the affected organ and the stage of the disease. Liver and lungs are the most commonly affected organs. The classic features of hepatic hydatid disease are well known. However, diagnosing hydatid disease at unusual locations may be challenging because of myriad imaging features in each of these locations. Knowledge of the imaging spectrum in systemic hydatidoses in various organs is very valuable in improving the accuracy of radiological interpretation. The purpose of this article is to review the imaging features of hydatid disease at its varied locations.
