Unusual presentation of severely disseminated and rapidly progressive hydatic cyst: Malignant hydatidosis

The infection caused by the tapeworm Echinococcus granulosus leads to the development of hydatic disease. It is the most frequent mediterranean parasitic infection that commonly affects the liver and rarely involves multiple organs. Herein, we report an exceptional and confusing presentation of hepatopulmonary and splenic hydatidosis due to Echinococcus granulosus that caused diagnostic problems occuring in a 70-year-old man, treated with chemotherapy, with favorable outcome. This was a very unusual case of disseminated hydatid cyst highlighting the interest of keeping a high level of clinical suspicion of this diagnosis every time we have a cystic lesion of the liver.
