Infectious disorders, cancer, and anti-neutrophil cytoplasm antibody-associated vasculitides are just a few of the clinical situations that can cause pulmonary nodular or cavitary lesions with cardiac thrombosis. In this case, we wanted to show how a hydatid cyst could resemble eosinophilic granulomatosis polyangiitis. A 15-yearold female patient was admitted to the hospital with a chronic cough and fatigue that had persisted for 1.5 years. Pulmonary nodules, cavitary lesions, and arterial thrombosis were found on thorax imaging, and cardiac thrombi were found on echocardiography, whereas acute phase reactants and eosinophil levels were elevated, and microscopic hematuria in urine test. These radiological and laboratory findings initially suggested eosinophilic granulomatosis with polyangiitis. A lung biopsy revealed no findings in favor of vasculitis, instead the hydatid cyst cuticle was seen. Hydatid cysts should be kept in mind in nodular/cavitary and thrombotic pulmonary involvement, and cardiac thrombus resembling vasculitis
