Alveolar echinococcosis localized in the liver, lung and brain.

chinococcosis is a parasitic disease caused by the larval forms of echinococci. It has two main forms as the unilocular cystic form that is more commonly seen and caused by E. granulosus and the alveolar form that is rarely seen and caused by E. multilocularis. E. multilocularis usually contaminates from foxes and sometimes contaminates from domestic animals as dogs and cats to humans and usually affects the liver. Progression of alveolar echinococcosis is more severe and agressive. It can metastise to the lungs, brain and bones. We present a case of alveolar echinococcosis that was initially thought to be a lymphomatous infiltration but then determined to infect the liver, lung and brain in a patient with a large T-cell lymphoma.
