CTICasesDisseminated Hydatid disease (Echinococcosis)
Imaging findings
CT scan of a young female from Peru shows a large, necrotic/cystic mass in the left lung apex showing peripheral calcification, and a similar calcified cystic mass in the liver.
Key takeaways
Hydatid disease is caused by Echinococcus granulosus and is endemic in sheep-farming regions (such as Peru). Pulmonary and hepatic cysts are common, and the presence of peripheral calcification indicates long-standing disease.
