Alveolar hydatid disease is a highly malignant form of echinococcosis caused by the larvae of the cestode Echinococcus multilocularis. Alveolar hydatid disease always affects the liver and can metastasise to the lungs and brain. The case reports describe the radiological features of alveolar hydatid disease of the lung caused by E. multilocularis. Multiple nodules which varied in size and shape were seen on CXR, CT showed most nodules to be lobulated, well circumscribed and of varying shape. Multiple lobulated lesions located between two segments of the lung and of varying shape appear to be characteristic of pulmonary alveolar hydatid disease caused by E. multilocularis.

D008875 Middle Aged An adult aged 45 - 64 years. Middle Age
D011650 Pulmonary Alveoli Small polyhedral outpouchings along the walls of the alveolar sacs, alveolar ducts and terminal bronchioles through the walls of which gas exchange between alveolar air and pulmonary capillary blood takes place. Alveoli, Pulmonary,Alveolus, Pulmonary,Pulmonary Alveolus
D004444 Echinococcosis, Hepatic Liver disease caused by infections with parasitic tapeworms of the genus ECHINOCOCCUS, such as Echinococcus granulosus or Echinococcus multilocularis. Ingested Echinococcus ova burrow into the intestinal mucosa. The larval migration to the liver via the PORTAL VEIN leads to watery vesicles (HYDATID CYST).
