CT Imaging Findings of Pulmonary Alveolar Echinococcosis

Alveolar echinococcosis is a parasitic infection caused by Echinococcus multilocularis in the metacestode stage. The disease involves the liver in almost all cases, and additionally, lung involvement is accompanied in approximately 13% of the cases. Due to the low incidence of pulmonary alveolar echinococci, there are few case reports of lung involvement in the literature. In this study, computed tomography (CT) findings related to pulmonary involvement in alveolar echinococcosis cases, which have increased worldwide in recent years, were evaluated.
