Cystic Echinococcosis of Liver and Spleen Communicating to the Lung: A Rare Case

Year: 2022

Type: article

Abstract: The annual cystic echinococcosis (CE) incidence in endemic countries is between 1 and 200 per 100,000 population. The clinical manifestations of CE are associated with damage or dysfunction of target organs and affect primarily the liver in around 70% of cases and lungs in around 20% of cases. The involvement of the spleen is rarely seen, representing 2 to 6% of all CE cases. We describe a 60-year-old female patient who presented with 15 days' history of intermittent fever and abdominal distension, having significant hepatosplenomegaly. CE was diagnosed involving the liver, spleen, and lungs and was confirmed radiologically and microbiologically. CE is caused by the larval or cystic stage of the zoonotic dog-tapeworm. Humans can be infected by ingestion of contaminated food or water. At present, there are nine species under the genus Echinococcus with E. granulosus sensu stricto having worldwide distribution, while the rest are focally distributed. CE involving multiple organs is rare. CE should be taken into consideration in patients with these symptoms in endemic areas.
