Incidental Finding of Pulmonary Hydatid Cyst in Patient with Neck of Femur Fracture

Echinococcosis is a rare infectious disease of human being that occurs by the larvalstages of taeniidcestodes of the genus Echinococcus. Cystic Echinococcosis may oftenbe diagnosed accidentally because the individual may remain asymptomatic for a longtime due to the silent nature of the pathogen. Human are the accidental host and usuallyaffected by handling an infected dog. The liver is the most frequently involved organ(65%) followed by lungs (25%). Characteristically the cysts are seen as solitary ormultiple circumscribed or Oval masses on imaging. Sometimes symptoms of hydatiddiseases like chest pain, breathlessness, expectoration, fever and hemoptysis can resultfrom the release of antigenic material and secondary immunological reactions thatdevelop from cyst rupture [1]. We report a case of incidental finding of PulmonaryHydatid Cyst presenting as Neck of Femur fracture. A middle aged female with chiefcomplaints of pain in the hip joint & unable to walk for 2 months was found to havedecreased breath sound in left infraclavicular& mammary area. Chest x-ray showedwell-defined homogenous opacity in left middle zone & some part of upper zone. TheCECT thorax showed a large well defined cystic lesion with regular margin &parenchymal consolidation around the cystic lesion with mild pleural effusion. Theliver parenchyma was normal. The patient was having leucocytosis with neutrophilia
