Diffuse abdominal hydatidosis: Role of magnetic resonance imaging

Hydatid cyst disease still is a serious public-health problem in endemic areas. It is a tissue infestation caused by the larval stage of a parasite, Echinococcus granulosus. Although liver and lung are the most commonly involved organs, hydatid disease can occur in all viscera and soft tissues. In 10% of cases, hydatid disease arises in the viscera: mainly in the spleen (0.9-8%), but also in kidney, bone, heart and peritoneal cavity (0.5-5%). Other rare locations such as muscles have been described in less than 1% of cases of hydatid disease. We report magnetic resonance imaging findings of a case of diffuse abdominal hydatidosis.
