[Ultrasonographic, CT, and MRI findings of chest wall hydatidosis]

The chest wall is an uncommon localization for hydatid disease even in countries where echinococcosis is endemic. Only isolated sporadic cases have been reported in the literature. We reviewed retrospectively 15 patients who underwent surgery for chest wall hydatid disease. Various imaging techniques were used for diagnosis of our cases. These included chest radiograph, thoracic ultrasonography, computed tomography and magnetic resonance imaging. Hydatid cyst involved soft tissues (n=5), ribs and vertebrae (n=5), ribs (n=4) and sternum (n=1). Imaging techniques were of value for diagnosis (radiographs and sonography) and for evaluation of the extent of involvement (CT and MRI). Chest wall hydatidosis requires surgical treatment but recurrence is frequent.
