We present an extremely rare case of a young man with hydatid pulmonary embolism caused by a direct invasion of the pulmonary artery by a hydatid cyst. Even if it is a benign parasitic disease, it can lead to serious complications such as arterial, systemic, or multivisceral dissemination or being responsible for an anaphylactic shock. Because of the clinical polymorphism, the diagnosis can be delayed. Therefore, it is necessary to know when conduct a chest CT angiography which is the gold standard for the positive diagnosis.
