PULMONARY ECHINOCOCCOSIS WITH EXTENSION TO SPLEEN AND LIVER IN A PATIENT WITH HAIRY CELL LEUKAEMIA AT THIRD RELAPSE

uman cystic echinococcosis is a widely endemic helminthic disease transmitted by dogs in livestock raising areas. It is a widely endemic helminthic disease worldwide in which humans are infected as 'aberrant' hosts by Echinococcus granulosus and develop cysts in numerous different organs. Clinicians, radiologists and pathologists should be aware of this entity and its pulmonary manifestations. Depending on their size and anatomic location, the cysts can eventually exert pressure on adjacent structures and be associated with unspecific symptoms like chronic cough, dyspnoea, pleuritic chest pain and haemoptysis. Differential diagnoses in the lungs include primary lung carcinoma and metastatic disease; related complications include pleuritis, lung abscess and pneumothorax.
