Echinococcosis is a parasitic infestation caused by the cestode of the genus Echinococcus. Man serves as an intermediate host and becomes infected by accidental ingestion of eggs from soil, water or by direct contact with the definitive host (dog). The present communication deals with two cases of echinococcosis of the lung. The presenting chief complaints were of breathlessness and dry cough. Routine haematological investigations revealed relative lymphocytosis in both the cases. However X-ray chest and CT showed a mass in the left lung in one case and a mass in the right lung in another case.  For further evaluation CT guided fine needle aspiration cytology (FNAC) was performed in case one and the final diagnosis of hydatid cyst lung was established. In another case surgery was performed. Histopathological examination, established the diagnosis of echinococcosis lung. Both the patients were treated accordingly and responded well to antihelminthic regime of therapy. DOI: 10.21276/APALM.1181
