Abstract

Metastatic hydatid disease of the lung may happen when a hydatid cyst (HC) anywhere in the body ruptures into a systemic vein, a right heart chamber or a pulmonary artery (PA), resulting in the embolisation of the cyst's contents into the lungs. We submit herewith, the images of embolised hydatids within the PA, in a patient who had surgery for HC involving the right ventricular (RV) wall in 2014. Despite adequate surgical and medical management, investigations in 2017 revealed multiple embolised cysts within PA branches. Further continued medical therapy resulted only in partial resolution of the disease, indicating probably the inadequacy of the currently available treatment strategies.

Keywords: Benzimidazole; Echinococcus granulosus; Hydatid cysts; Pulmonary embolism; Syncope.
