Hydatid cyst is an infectious disease caused by the parasite Echinococcus. Humans are accidentally infected. Mostly, the cyst remains dormant without causing any symptoms. The cyst can cause complications after rupture or due to mass effect. Imaging studies such as X-ray, CT, and MRI can be indicative of a hydatid cyst, but they are not reliable. Carefully performed fine needle aspiration cytology has gained importance in the definitive diagnosis of hydatid cyst because of its advantages, such as minimal invasiveness, rapidness, and simplicity of the procedure. We present a case of an isolated pulmonary hydatid cyst where Fine Needle Aspiration Cytology (FNAC) was effectively utilized for diagnosis.
