Cyst hidatic is a parasitic infestation created by Echinococcus granülosus. This study presented a phenomenon in the malignant mass appearance, which is beyond the classic radiological and bronchoscopic appearances of the lung cyst direction. A 17-year-old male patient applied with cough, swelling, blood sputum complaints. The patient lost 10 kg in the last 2 months. The patient with a computational tomography of the throat was diagnosed with a fiberoptic bronchoscopy. In the fiberoptic bronchoscope, the upper lob frontal segment of the right liver has seen mucous totality and damages covered by the necrotic tissue above. The endobronchial biopsy result was as "cyst hidatic". In the Western ultrasound, epigastrium found cystic formation in the left lobe of the liver. The patient was transferred to the breast surgical clinic for surgery. With the operation there, the cyst in the lungs was removed. Lung cyst guidelines are often localized in the lower lobes. Although cysts are classical radiological, bronchoscopic findings, it is necessary to take the mind of cyst guidance in different radiological, bronchoscopic appearances, although rare.
